Question

I am trying to write a function that as input takes a string containing words and removes all single character words and returns the new string without the removed characters

E.g.:

string news = FunctionName("This is a test");
//'news' here should be "This is test".

Can you please help?

I’m sure there’s a nicer answer using regex, but you could do the following:

string[] words = news.Split(' ');

StringBuilder builder = new StringBuilder();
foreach (string word in words)
{
    if (word.Length > 1)
    {
       if (builder.ToString().Length ==0)
       {
           builder.Append(word);
       }
       else
       {
           builder.Append(" " + word);
       }
    }
}

string result = builder.ToString();
