Set property Nullable<> by reflection

Question

I try to set a Nullable<> property dynamicly.

I Get my property ex :

PropertyInfo property = class.GetProperty(\"PropertyName\"); // My property i

If it's a nullable int, you'll need to use an int parameter, not a string.

 property.SetValue(klass,1256,null);

Note the change to klass, instead of class, as class is a reserved keyword. You could also use @class if absolutely necessary (quoting it).

If your property is a generic, then I think you'll probably need to use Convert to convert whatever you have to whatever you need.

 var nullType = Nullable.GetUnderlyingType(property.PropertyType)
 var value = Convert.ChangeType("1256", nullType );
 property.SetValue(klass, value, null );
