 1, taken with the separated split a single character

string str = "GT123_1";
string[] strArray = str.Split('_');
//输出：sArray[0]="GT123"
//     sArray[1]="1"

string str = "GTAZB_JiangjBen_123";
string[] strArray = str.Split(new char[2] { 'j', '_' });
//输出：sArray[0]="GTAZB"
//     sArray[1]="Jiang"
//     sArray[2]="Ben"

//     sArray[1]="ang"
//     sArray[2]="en_123"。

string str = "GTAZB_JiangjBen_123";
int start = 3, length = 8; 
Console.WriteLine(str.Substring(start - 1, length));
//输出：AZB_Jian。

5, the character string is extracted from the right of a string of length i

string str = "GTAZB_JiangjBen_123";

str = str.Substring(str.Length - i);
Console.WriteLine(str);
//输出：n_123。

6, a specific character string in the replacement string

string str = "GTAZB_JiangjBen_123";
str = str.Replace("123", "321");
