Roslyn - Parse string to MethodDeclarationSyntax

Question

Is there any function in Roslyn, by which I can parse my string as a MethodDeclarationSyntax?

I have a file which contains the method declaration, so I am reading that file content to string and now I want to create a Method from that string. Any suggestions?

One option is to parse your string as "C# Script", an experimental version of C# that allows top-level method declarations. Doing:

var tree = SyntaxTree.ParseText("void Foo() {}", options: new ParseOptions(kind: SourceCodeKind.Script));

Gives you a valid syntax tree that contains a CompilationUnitSyntax of a single method declaration.
