如何在TextBox1.Text中禁用空格键？

问题描述

大家好，我回来了。



首先，我要感谢你给我的正规表达，它很高兴地解决了我的问题。：笨蛋：



现在，在对数组进行排序之前，我从TextBox1.Text中获取值（例如，323,1,65,7,3,999,0，）。 />


我如何禁用此控件中的空格来限制用户提供不需要的空格？我只需要数字和逗号。：confused：



谢谢

Hi guys, am back.

First i need to thank you for the "regula expression" given to me ealier, it happily solved my problem.:thumbsup:

NOW, before sorting an array I get values from TextBox1.Text like(eg. 323,1,65,7,3,999,0,).

HOW can i disable the use of spaces in this control to restrict the user from giving unwanted spaces? I need only numbers and commas.:confused:

Thanks

推荐答案

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

通过将Handled设置为true，此字符不会反映在文本框中。顺便说一句 - 请为你的变量命名，而不是VS给你的默认值。 TextBox1现在对你来说似乎不会太糟糕，但是你会记得它在6个月内的用途吗？

By setting Handled to true, this character won't be reflected in the textbox. BTW - please name your variables better than the default values that VS gives you. TextBox1 won't seem too bad to you now, but will you remember what it's for in 6 months time?

this.KeyPreview = true;

e.Handled = (e.KeyChar = " ")

此外，它不使用分号来结束行。

Also, it doesn't use semicolons to end lines.
