How can I find all signatures(overloads) of a method in Roslyn in a class or partial class files?

Via Roslyn, C# syntax ,I have IMethodSymbol to clarify my method information,

var symbolMethod = context.SemanticModel.GetSymbolInfo(invocation).Symbol as IMethodSymbol;

if (symbolMethod == null) return;
//-- Here I need to get other signature of the symbolMethod

Notation: the container class maybe has partial class which includes some signature of this method

var symbolMethod = context.SemanticModel.GetSymbolInfo(invocation).Symbol as IMethodSymbol;
//has several signatures
if (symbolMethod.ContainingType.GetMembers().Count(it => it.Name == symbolMethod.Name) > 1)

You could look into SemtanticModel.GetMemberGroup:

var overloads = model.GetMemberGroup(invocation.Expression);

It returns a list of overloads of the method

Just do symbolMethod.ContainingType, and from there you can call GetMembers to get all members of the type. You can filter by name or whatever you're looking to get from there.
