Prefix spaces for each line in a string 2016-06-12

My code generator requires to generate code with right indentation, so I need to prefix spaces for each line of a string. After google the world, there isn’t a out-of-box solution for me to use, finally I came up with my own solution:

internal static string Indent(this string content, int level = 1) =>
    string.Join(Environment.NewLine, content
        .Split(new[] { "\r\n" }, StringSplitOptions.None)
        .Select(_ => $"{(_ == string.Empty ? string.Empty : new string(' ', level * 4))}{_}")
        .ToArray());

Usage like this:

var result = str.Indent();

Use Roslyn to generate semantic code 2016-06-12

Scenario: I have made some utilities to generate C# code, however, I just utilize literal string with string.format, which is not good enough after Roslyn come out. So I tried to generate semantic code using Roslyn.
