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;
