c# - 如何处理asp.net中的textchange事件

Question

请帮助我如何处理asp.net 中的TextChange事件。早期的respose高度赞赏。

string str = this.txtLog.Text.ToString();
int startPos = str.LastIndexOf("UID:") + "UID:".Length + 1;
int length = str.IndexOf("Sector") - startPos;
string sub = str.Substring(startPos, length);
readerUID = sub;

this.txtLog.TextChanged += txtLogTextChanged;  

protected void txtLogTextChanged(object sender, EventArgs e)
{
   //do whatever you want on text changed
}
