A small usage of String. Join

It is often necessary to concatenate an array or List item into a string using a separator. The general implementation logic is to connect through members + delimiters, and then intercept the last Separator in the result. Suddenly, we found that the String. Join method implements this function. A simple example outputs a, B, c

[Csharp]
Class Program
{
Static void Main (string [] args)
{
List <string> list = new List <string> ();
List. Add ("");
List. Add ("B ");
List. Add ("c ");
 
Console. WriteLine (string. Join (",", list ));
Console. ReadKey ();
}
}
