c# reflection get static property value
You can use C# reflection to get the value of a static property by following these steps:
- Get the Type object that represents the class that contains the static property using the typeof operator or the GetType method.
- Get the PropertyInfo object that represents the static property you want to access using the GetProperty method of the Type object. Make sure to specify BindingFlags.Static | BindingFlags.Public to indicate that you’re looking for a static property that is public.
- Use the GetValue method of the PropertyInfo object to get the value of the static property. Since this is a static property, you can pass null as the first argument to the GetValue method.
Here’s an example code snippet that demonstrates how to get the value of a static property using reflection:
using System;
using System.Reflection;
public class MyClass
{
public static int MyStaticProperty { get; set; } = 42;
}
class Program
{
static void Main(string[] args)
{
Type type = typeof(MyClass);
PropertyInfo propertyInfo = type.GetProperty("MyStaticProperty", BindingFlags.Static | BindingFlags.Public);
int value = (int)propertyInfo.GetValue(null);
Console.WriteLine(value); // Output: 42
}
}
In this example, we define a class named MyClass that contains a public static property named MyStaticProperty. In the Main method, we use reflection to get the value of MyStaticProperty and then print it to the console.

In C#, you can use reflection to get the value of a static property using the System.Reflection namespace. Here’s an example of how to do it:
In this example, we have a class MyClass that has a static property called MyStaticProperty. We use the typeof operator to get a System.Type object representing the MyClass type, then we use the GetProperty method of that Type object to get a System.Reflection.PropertyInfo object representing the MyStaticProperty property.
Once we have the PropertyInfo object, we can use the GetValue method to get the value of the property. We pass null as the argument to GetValue because the property is static and doesn’t belong to an instance of the class. Finally, we cast the result to an int because MyStaticProperty is an int.
Note that you can also use the PropertyInfo.GetValue method without passing the instance parameter if you’re getting a static property value:
This code does the same thing as the previous example, but it’s a little more concise.
