✅ How can i turn this into a query?

Current code: foreach (var type in module.Types) { if (type.Name == "foo") { foreach (var method in type.Methods) { if (method.Name == "bar") MethodDefinition myMethod = method; } } } I am trying to turn this code into a query, so it's shorter and prettier.. but i can't seem to get it right.. MethodDefinition myMethod = from type module.Types where type.Name == "foo" ... I just get errors with whatever i try..

module.Types
  .Where(t => t.Name == "foo")
  .SelectMany(t => t.Methods)
  .Where(m => m.Name == "bar")

module.Types
  .Where(t => t.Name == "foo")
  .SelectMany(t => t.Methods)
  .Where(m => m.Name == "bar")

something like this I guess

Where do i put the assignment of: MethodDefinition myMethod = method ?

what is this for?

I need to get the myMethod reference, so i can pass it as an argument to a different function it's from mono.cecil library using it to inject .net code into a .net binary

dont know much about this mono lib, but if you need all them to pass, use

var methods = module.Types
  .Where(t => t.Name == "foo")
  .SelectMany(t => t.Methods)
  .Where(m => m.Name == "bar");

foreach(var method in methods)
{
  DifferentFunction(method); // ?
  method.Invoke(); // ?
}

var methods = module.Types
  .Where(t => t.Name == "foo")
  .SelectMany(t => t.Methods)
  .Where(m => m.Name == "bar");

foreach(var method in methods)
{
  DifferentFunction(method); // ?
  method.Invoke(); // ?
}

Oh i thought it would select only one.. ok i think i understand my mistake Yes that looks very good mono lib is amazing btw

if you need only one, then use .FirstOrDefault()
