C#截取字符串后几位

要在C#中截取字符串的后几位，有几种方法可以实现。

第一种方法是使用`Substring`函数。首先，将字符串赋值给一个变量，然后使用`Substring`函数来截取字符串的后几位。例如，如果要截取字符串的后5位，可以使用以下代码：

string str = "GTAZB_JiangjBen_123";
int i = 5;
string tSt = str.Substring(str.Length - i);
Console.WriteLine(tSt);

这将输出 "n_123"。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
