Is there a method in C# to check if a string is a valid identifier

Question

In Java, there are methods called isJavaIdentifierStart and isJavaIdentifierPart on the Character class that may be used to tell if a string is a valid Java identifier, like so:

public boolean isJavaIdentifier(String s) {
  int n = s.length();
  if (n==0) return false;
  if (!Character.isJavaIdentifierStart(s.charAt(0)))
      return false;
  for (int i = 1; i < n; i++)
      if (!Character.isJavaIdentifierPart(s.charAt(i)))
          return false;
  return true;
}

Is there something like this for C#?

Answer 1

Yes:

// using System.CodeDom.Compiler;
CodeDomProvider provider = CodeDomProvider.CreateProvider("C#");
if (provider.IsValidIdentifier (YOUR_VARIABLE_NAME)) {
      // Valid
} else {
      // Not valid
}
