Hi, suppose I have a string

as e.g: "Var_str"

I need to check whether the string contains only "Var_Str" or it is appended by some more string

for example "Var_str_Value" or "Var_str_Var_Variable" or "Var_str.Comment"...

Please help on this.

推荐答案

if (myStringVariable.StartsWith("Var_str") && !myStringVariable.Equals("Var_str"))
{
    //There is something more to be seen
}

您可以尝试此代码。如果返回true，则没有额外的字符串。这里str是一个变量，它有一个需要验证的字符串。

You can try this code. If this returns true then there are no extra string. Here str is a varible which has a string that needs to be verified.

str.Replace("Var_str",string.Empty)==string.Empty

试试这个

Try this

const string s = "Var_str_Value";
          var result = s.Replace("Var_str","");
          if(result.Trim().Length>0)
          {
              //Contain more than characters
          }

希望这有助于
