How to use ASP. NET string Truncation

Two practical methods for string truncation (automatic line feed beyond a certain length)
1 /**////
2 // intercept a string without specifying the length of the string
3 ///
4 // the string to be intercepted
5 // The length of each line, more than the length of this line automatically wrap
6 ///
7 public string CutStr (string str, int len)
8 {string s = "";
9
10 for (int I = 0; I 11 {
12 int r = I % len;
13 int last = (str. Length/len) * len;
14 if (I! = 0 & I <= last)
15 {
16
17 if (r = 0)
18 {
19 s + = str. Substring (I-len, len) +"
";
20}
21
22}
23 else if (I> last)
24 {
25 s + = str. Substring (I-1 );
26 break;
