删除文本框中的最后一个字符

问题描述

这是我的代码段.

This is my code snippet.

for(int i=0; i<=textbox.text.length;i++)
{
textbox.text.tostring[i].tostring;
int index=textbox.text.tostring.lastindexof(",");
if(i.equals(index))
 {
  textbox.text=textbox.text.remove(index, 1);
  }
}

我在文本框中碰巧有许多电子邮件地址，格式为me @ yahoo.com，you @ yahoo.com，但我只需要删除最后一个字符(，).问题在于它会删除两个字符.

I happen to have a number of email addresses in a textbox in this format [email protected], [email protected], but i need to delete the last character(,) only. The problem is it deletes both characters.

推荐答案

textbox.Text.Remove(textbox.Text.LastIndexOf('',''),1);

它更简单的方法，您可以在任何需要使用它的事件中使用它

希望我能帮忙

its easier way and you can use it in whatever the event you would like to use it in

I hope I helped
:-)

textbox.Text = textbox.Text.Remove(Textbox.Text.LastIndexOf('',''), 1);

String orgText = textbox.text;
int i = orgText.LastIndexOf(",");
if(i != -1)
{
textbox.text = orgtext.Remove(i);
}
