Практическое руководство. Выделение текста в элементе управления TextBox в Windows Forms How to: Select Text in the Windows Forms TextBox Control

Текст можно выбрать программным способом в TextBox элементе управления Windows Forms. You can select text programmatically in the Windows Forms TextBox control. Например, при создании функции, выполняющей поиск определенной строки в тексте, можно выбрать текст, чтобы визуально предупредить читателя о положении найденной строки. For example, if you create a function that searches text for a particular string, you can select the text to visually alert the reader of the found string’s position.

Выбор текста программным способом To select text programmatically

Задайте SelectionStart для свойства начало текста, который необходимо выбрать. Set the SelectionStart property to the beginning of the text you want to select.

SelectionStartСвойство является числом, указывающим точку вставки в текстовой строке, а 0 — самое левое положение. The SelectionStart property is a number that indicates the insertion point within the string of text, with 0 being the left-most position. Если SelectionStart для свойства задано значение, равное числу символов в текстовом поле или больше, то точка вставки помещается после последнего символа. If the SelectionStart property is set to a value equal to or greater than the number of characters in the text box, the insertion point is placed after the last character.

Задайте SelectionLength для свойства длину текста, который необходимо выбрать. Set the SelectionLength property to the length of the text you want to select.

SelectionLengthСвойство является числовым значением, которое задает ширину точки вставки. The SelectionLength property is a numeric value that sets the width of the insertion point. Если задать SelectionLength для параметра значение больше 0, будет выбрано количество символов, начиная с текущей точки вставки. Setting the SelectionLength to a number greater than 0 causes that number of characters to be selected, starting from the current insertion point.

Используемых Доступ к выбранному тексту осуществляется через SelectedText свойство. (Optional) Access the selected text through the SelectedText property.

Приведенный ниже код выбирает содержимое текстового поля при Enter возникновении события элемента управления. The code below selects the contents of a text box when the control’s Enter event occurs. В этом примере проверяется, имеет ли текстовое поле значение для Text свойства, которое не равно null или является пустой строкой. This example checks if the text box has a value for the Text property that is not null or an empty string. Когда текстовое поле получает фокус, выделяется текущий текст в текстовом поле. When the text box receives the focus, the current text in the text box is selected. TextBox1_Enter Обработчик событий должен быть привязан к элементу управления. Дополнительные сведения см. в разделе как создавать обработчики событий во время выполнения для Windows Forms. The TextBox1_Enter event handler must be bound to the control; for more information, see How to: Create Event Handlers at Run Time for Windows Forms.

Чтобы протестировать этот пример, нажимайте клавишу TAB, пока текстовое поле не найдет фокус. To test this example, press the Tab key until the text box has the focus. Если щелкнуть в текстовом поле, то текст не будет выбран. If you click in the text box, the text is unselected.

How to remove ‘System.Windows.Forms.TextBox, Text:’ from message and text

I have written a simple program in C# in which

1. messages are displayed using a statement like:

Some text box contents are written to text files using StreamWriter. In both case, in addition to the correct content, I also get the prefix: System.Windows.Forms.TextBox, Text:

I get a similar prefix (and a suffix of \r\n) when using StreamReader to read the contents of a text file.

How do I avoid this?

2 Answers 2

Without seeing your code, I’m guessing you’re passing the TextBox directly to the StreamWriter , rather than passing the TextBox.Text property value. Passing the TextBox reference directly to StreamWriter.WriteLine will call TextBox.ToString() to get a string value that it can write, and it looks like TextBox.ToString() is generating that prefix. Pass in TextBox.Text , and you shouldn’t see it anymore.

The best and easiest soloution to this i have ever found is to split the string and use the required string

Try this code hope this will work

Text Box Class

Definition

Represents a Windows text box control.

Examples

The following code example creates a multiline TextBox control with vertical scroll bars. This example uses the AcceptsTab, AcceptsReturn, and Dock properties to make the multiline text box control useful for creating text documents.

Remarks

With the TextBox control, the user can enter text in an application. This control has additional functionality that is not found in the standard Windows text box control, including multiline editing and password character masking.

Typically, a TextBox control is used to display, or accept as input, a single line of text. You can use the Multiline and ScrollBars properties to enable multiple lines of text to be displayed or entered. Set the AcceptsTab and AcceptsReturn properties to true to enable greater text manipulation in a multiline TextBox control.

You must set the Multiline property to true to adjust the height of the TextBox control. You can adjust the height by setting the Size property.

You can limit the amount of text entered into a TextBox control by setting the MaxLength property to a specific number of characters. TextBox controls can also be used to accept passwords and other sensitive information. You can use the PasswordChar property to mask characters entered in a single-line version of the control. Use the CharacterCasing property to enable the user to type only uppercase, only lowercase, or a combination of uppercase and lowercase characters into the TextBox control.

To scroll the contents of the TextBox until the cursor (caret) is within the visible region of the control, you can use the ScrollToCaret method. To select a range of text in the text box, you can use the Select method.

To restrict text from being entered in a TextBox control, you can create an event handler for the KeyDown event in order to validate each character entered in the control. You can also restrict all entry of data in a TextBox control by setting the ReadOnly property to true .

Most of the functionality of the TextBox control is inherited from the TextBoxBase class.

Using the TextBox control with visual styles enabled will cause the incorrect handling of surrogate fonts.
