.NET Framework Expression Trees Expression for retrieving a static field
Example
Having example type like this:
public TestClass
{
public static string StaticPublicField = "StaticPublicFieldValue";
}
We can retrieve value of StaticPublicField:
var fieldExpr = Expression.Field(null, typeof(TestClass), "StaticPublicField");
var labmda = Expression.Lambda<Func<string>>(fieldExpr);
It can be then i.e. compiled into a delegate for retrieving field value.
Func<string> retriever = lambda.Compile();
var fieldValue = retriever();
//fieldValue result is StaticPublicFieldValue
