C # Expression Tree Tips

Question

I am working on a method that takes an expression tree as a parameter along with the type (or instance) of a class.

The basic idea is that this method will add certain things to the collection that will be used for validation.

public interface ITestInterface
{
    //Specify stuff here.
}

private static void DoSomething<T>(Expression<Func<T, object>> expression, params IMyInterface[] rule)
{
    // Stuff is done here.
}

The method is called as follows:

class TestClass
{
    public int MyProperty { get; set; }
}

class OtherTestClass  : ITestInterface
{
    // Blah Blah Blah.
}

static void Main(string[] args)
{
    DoSomething<TestClass>(t => t.MyProperty, 
        new OtherTestClass());
}

I do it this way because I would like the names of the properties that were passed to be strong.

A few things I struggle with.

• DoSomething PropertyInfo ( ) T []. .Body [propertyname] "Convert. ([Propertyname])" , , . . ?
• , ?
• , , , / #, .

:

, expression.Body.ToString() DoSomething, , "Convert (t.MyProperty)", .
