Get an acronym from a string in C# using LINQ?

Question

Here is how I would write a function to make an acronym in Java style:

    string makeAcronym(string str)
    {
        string result = \"\";
        for (in

LINQ can work for this but generally I find it's better to build up string values using StringBuilder instance. This allows you to avoid unnecessary string allocations.

string makeAcronym(string str) { 
  var builder = new StringBuilder();
  for ( var i = 0; i < str.Length; i++ ) { 
    var c = str[i];
    if ( c == ' ' ) {
      continue;
    }
    if ( i == 0 || str[i-1] == ' ' ) {
      builder.Append(c);
    }
  }
  return builder.ToString();
}
