Verify that an object has a certain property

Question

I found C# code for it here

So I tried

Public Function checkProperty(ByVal objectt As Object, ByVal propertyy As String) As Boolean
    Dim type As Type = objectt.GetType
    Return type.GetMethod(propertyy)
End Function

But it throws an error at type.GetMethod(propertyy) saying "Value of type 'System.Reflection.MethodInfo' cannot be converted to 'Boolean'."

What to do?

Answer 1

First, C# code checks for presence of a method, not a property. Second, C# code compares return to null:

Public Function checkProperty(ByVal objectt As Object, ByVal propertyy As String) As Boolean
    Dim type As Type = objectt.GetType
    Return type.GetProperty(propertyy) IsNot Nothing
End Function

EDIT To check for fields, change the method as follows:

Public Function checkField(ByVal objectt As Object, ByVal fieldName As String) As Boolean
    Dim type As Type = objectt.GetType
    Return type.GetField(fieldName) IsNot Nothing
End Function

Answer 2

it is returning the MethodInfo instead and you can just change it as follow:

Public Function checkProperty(ByVal objectt As Object, ByVal propertyy As String) As Boolean
    Dim type As Type = objectt.GetType
    Return type.GetMethod(propertyy) IsNot Nothing
End Function
