C#刪除字符串最后一個字符的幾種方法

案例：刪除字符串中的最后一個字符

string s = "8,2,3,7,9,"  //處理后變成 “8,2,3,7,9”

方法一：使用Substring

string s = "8,2,3,7,9,"
s = s.Substring(0,s.Length - 1)

方法二、用TrimEnd,這個方法傳遞的是一個字符數組

string s = "8,2,3,7,9,"
s=s.TrimEnd(',')
//如果要刪除"9,"，則需要這么寫
char[] MyChar = {'9',','};
s = s.TrimEnd(MyChar);

方法三、用Remove

string s = "8,2,3,7,9,"
s = s.Remove(a.Length - 1,1); //移除掉","
