How to Escape Strings for C# String Literals?

C# string Words to rigid the righteousness guidelines

In C#, the string word is represented by dual quotes. These literal quantities can use the rigid sequence (for example, T represents the formula, n represents the change symbol) to indicate special characters.

Convert the ordinary string to its righteous string representing form, you can consider the following methods:

Use code to generate

Using code generation technology, you can use CodedomProvider to generate the required string of string:

<code class="language-csharp">private static string ToLiteral(string input)
{
    using (var writer = new StringWriter())
    {
        using (var provider = CodeDomProvider.CreateProvider("CSharp"))
        {
            provider.GenerateCodeFromExpression(new CodePrimitiveExpression(input), writer, null);
            return writer.ToString();
        }
    }
}</code>

This method follows the following steps to create a facade string representation form:

Create a stringwriter to capture generated code.
Use CodedomProvider to generate code from the original expression of the input string.
Extracted the generated code from StringWriter.

Using Roslyn's Symboldisplay

A update method is to use Roslyn's microsoft.codeanalysis.csharp Nuget package:

<code class="language-csharp">private static string ToLiteral(string valueTextForCompiler)
{
    return Microsoft.CodeAnalysis.CSharp.SymbolDisplay.FormatLiteral(valueTextForCompiler, false);
}</code>

This method generates the procedure by using Roslyn's Symboldisplay to generate the string of the righteousness, simplifying the process.
