code for clearing all textbox in a form c#

推荐答案

其他解决方案没有考虑控件可以嵌套（我个人总是放一个数字面板（分离器等）并添加其他控件作为Panel的子项。）



因此，解决方案需要递归：

The other solutions do not take into account that the controls can be nested (I personally always put a number of Panels (splitters, etc.) and add other controls as Panel's children).

So, the solution needs to be recursive:

void ClearTextBoxes(Control parent) {
    foreach (Control child in parent.Controls) {
        TextBox textBox = child as TextBox;
            if (textBox == null)
                ClearTextBoxes(child);
            else
                textBox.Text = string.Empty;
    } //loop
} //ClearTextBoxes

//...

ClearTextBoxes(myForm);

< dd> -SA

尝试：

Try:

foreach (Control c in Controls)
   {
   TextBox tb = c as TextBox;
   if (tb != null)
      {
      tb.Text = string.Empty;
      }
   }

试试这个：

Try this:

foreach (TextBox t in this.Controls.OfType<TextBox>())
            {
                t.Text = string.Empty;
            }
