推荐答案

假设您能够从 GridView 中获取字符串，您只需使用 String.Su bstring 方法，例如

Assuming you are able to get the string from the GridView, you have just to use String.Substring method, e.g.

public static string Collapse(string str)
{
  if (str.Length <= 2) return str;
  return str.Substring(0,1) + str.Substring(str.Length-1);
}
public static void Main()
{
  string [] a = { "fox", "go", "b", "", "12344560"};

  foreach (string s in a)
      Console.WriteLine("{0}, {1}", s, Collapse(s));
}
