选择 属性 无效
Selection property not working
string holder = richTextBox1.Selection.Text;
.Selection
产生错误:
'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?).
A RichtTextBox
没有 Selection
属性,因此出现错误消息。
它确实有一个 SelectionStart
and SelectionLength
属性,您可以使用它来自己获取选择文本:
string selectedText = rtb.Text.Substring(rtb.SelectionStart, rtb.Length);
或者直接使用SelectedText
string selectedText = rtb.SelectedText;
string holder = richTextBox1.Selection.Text;
.Selection
产生错误:
