FieldInfo has an IsStatic member, but PropertyInfo doesn't. I assume I'm just overlooking what I need. 

Type type = someObject.GetType();

foreach (PropertyInfo pi in type.GetProperties())
{
   // umm... Not sure how to tell if this property is static
}

To determine whether a property is static, you must obtain the MethodInfo for the get or set accessor, by calling the GetGetMethod or the GetSetMethod method, and examine its IsStatic property.

As an actual quick and simple solution to the question asked, you can use this:

propertyInfo.GetAccessors(nonPublic: true)[0].IsStatic;

Better solution

public static class PropertyInfoExtensions
{
    public static bool IsStatic(this PropertyInfo source, bool nonPublic = false) 
        => source.GetAccessors(nonPublic).Any(x => x.IsStatic);
}

Usage:

property.IsStatic()

Why not use 

type.GetProperties(BindingFlags.Static)

  • Nice! However, in my case I want the non-static which doesn't seem to have a binding flag. – CrashCodes Dec 24 '08 at 20:40
  • This will not give you the static binding flag of the getter – Alfredo A. May 31 '18 at 15:51

    This is not a valid solution. First of all, it does not even list static properties, because binding flags should also have access level specified (`BindingFlags.Public`, `BindingFlags.NonPublic`, or both). Second of all, this simply lists static properties (input is `Type`, output is `PropertyInfo[]`), whereas the question is "given a property, how to determine if it is static?" (input is `PropertyInfo`, output is `bool`). I guess the closest thing to your proposal would be to slap `.Contains(property)` at the end, but I'd argue it would be a sub-optimal solution. – Grx70 Jan 17 '21 at 12:08
