Anybody help me how to write the code please?
答
尝试一下:
Try this:
string _text = text1.box;
int _location = text.IndexOf(@"n"); _location将包含"n"的位置.
_location will contain the location of ''n''.
字符串str = TextBox1.Text;
int position = str.IndexOf(TextBox2.Text)+1;
Label1.Text = position.ToString();
使用它，您将获得我使用+1的结果，因为索引从0开始.
string str = TextBox1.Text;
int position = str.IndexOf(TextBox2.Text)+1;
Label1.Text = position.ToString();
use it u will get the result i used +1 as indexing starts from 0.
