在文本框中用另一个（，）更改键盘输入（。） [英] Changing a keyboard entry (.) by another (,) in a textbox

问题描述

你好，

 我想在文本框控件中输入禁用字符时进行自动更改...我的数据库只接受逗号分隔符以获取金钱和美分条目。所以，每当
我按下键盘上的点时，我想自动更改此字段中逗号的点。非常感谢你的帮助。

 I want to make an automated change when I enter a forbidden character in a textbox control... My database accepts only a comma separator for money and cents entries. So, I would like to change the dot for a comma in this field automatically whenever I press the dot on my keyboard. Many thanks for your help.

推荐答案

请处理"KeyPress"在TextBox中输入事件，如果按下[。]（句点）键，请将其替换为[，]（逗号）。 



[VB。 NET]

Hi,

Please handle "KeyPress" event in TextBox, and if [.] (period) key is pressed, replace it with [,] (comma). 

[VB.NET]

Private Sub TextBox1_KeyPress(sender As Object, e As KeyPressEventArgs) Handles TextBox1.KeyPress
	If (e.KeyChar = ".") Then
		e.KeyChar = ","
	End If
End Sub

[C＃]

[C#]

private void TextBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    if ((e.KeyChar == "."))
    {
        e.KeyChar = ",";
    }
}

问候，

Regards,
