TextBox选择不当 [英] TextBox selection improper

问题描述

大家好，

在TextBox中，我将文本设置为"21-01-1992"。当我双击文本"01"时，只有文字"01"。已选中。

In TextBox, I have set the text as "21-01-1992" When I double click on the text "01" only the text "01" is selected.

但是，如果我将文本设置为"21 // 01/1992"双击文本"01" TextBox中的整个文本被选中。我可以只选择文字"01"吗？以上述格式。

But, If I set the text as "21//01/1992" on double click on the text "01" The whole text in the TextBox gets selected. Can I select only the text "01" in this format as like above.

问候，

您好Kumaran619，

Hi Kumaran619,

为此你首先得到光标位置，然后选择长度，请参考下面的代码：

For this purpose you should get the cursor position first, then select length, please refer to the below code:

        private void textBox2_DoubleClick(object sender, EventArgs e)
        {
            int a = this.textBox2.GetCharIndexFromPosition(this.textBox2.PointToClient(Cursor.Position));//get cursor
            textBox2.Select(a-1, 2);//cursor-1(start position) select-length
        }

您可以使用此方法自定义任何位置和长度。

You can customize any position and length from this method.

希望这会有所帮助！

最诚挚的问候，

Stanly
