Check if property has attribute

Question

Given a property in a class, with attributes - what is the fastest way to determine if it contains a given attribute? For example:

    [IsNotNullable]
    [I         


        

Answer 1

You can use the Attribute.IsDefined method

https://msdn.microsoft.com/en-us/library/system.attribute.isdefined(v=vs.110).aspx

if(Attribute.IsDefined(YourProperty,typeof(YourAttribute)))
{
    //Conditional execution...
}

You could provide the property you're specifically looking for or you could iterate through all of them using reflection, something like:

PropertyInfo[] props = typeof(YourClass).GetProperties();
