如何清除C#中TextBox中的所有数据/字符串 [英] How to clear all data / string in a TextBox in C#

问题描述

我在谷歌上快速浏览了一下，没有找到任何简单的东西.

I have had a quick look on Google and didn't pull anything simple up.

我试过了:

textBox5.Clear();

textBox5.Text=("");

textBox5.Text="".ToString();

推荐答案

你可以试试:

 foreach ( Control ctl in Parent.Controls) {
 if (ctl.GetTyep()== TextBox)
        ctl.text = ""; 
 } 

还有你为什么要这样做

    textbox.Text = (""); //You don't need the parenthesis here
    textbox.Text = "".toString(); //the .toString() is definitly not needed.

如果你只想要一个文本框，那么:

If you only want it for a single textbox then:

myTextBox.Text = String.Empty; 

或

 myTextBox.Text = "";
