选择属性不起作用 [英] Selection property not working

问题描述

string holder = richTextBox1.Selection.Text;

.Selection 产生错误:

System.Windows.Forms.RichTextBox"不包含Selection"的定义，并且找不到接受System.Windows.Forms.RichTextBox"类型的第一个参数的扩展方法Selection"(您是否遗漏了)是 using 指令还是程序集引用?).

'System.Windows.Forms.RichTextBox' does not contain a definition for 'Selection' and no extension method 'Selection' accepting a first argument of type 'System.Windows.Forms.RichTextBox' could be found (are you missing a using directive or an assembly reference?).

推荐答案

RichtTextBox 没有 Selection 属性，因此出现错误消息.

A RichtTextBox doesn't have a Selection property, hence the error message.

它确实有一个 SelectionStart 和 SelectionLength 属性，您可以使用它自己获取选择文本:

It does have a SelectionStart and SelectionLength property, which you can use to get the selection text yourself:

string selectedText = rtb.Text.Substring(rtb.SelectionStart, rtb.Length);

或者简单地使用 SelectedText

Or simply use SelectedText

string selectedText = rtb.SelectedText;
