How to pass an Object type to Type parameter in C#

Question

I have a function that has Type Parameter.

public static object SetValuesToObject(Type tClass, DataRow dr)
{
   //
   .............
   //
   return object
}

I have no idea how to pass a class as parameter for this function. Here i want to pass parmeter Class "Product".

I tried this

 SetValuesToObject(Product,datarow);

But it doesn't work. How could i do this?

The typeof keyword when you know the class at compile time.

SetValuesToObject(typeof(Product),datarow);

You can also use object.GetType() on instances that you don't know their type at compile time.

This saved me! You point out an important distinction about what's known at compile time and what's not. object.GetType() is what I needed. – Scott Ridings May 26 '20 at 13:28

You have a few options:

instance.GetType() : this method (defined in Object) will return the instance's type.
typeof(MyClass) : will give you the type for a class.

Finally, if you own the method, you could change it to use Generics, and call it like this instead

SetValuesToObject<Product>(datarow)
