Check if object is Byte[]

Question

How to check if the object is byte[] using a reflection? I use this line of code to check typeof(T).GetType().Equals(typeof(byte[])) but it didn't work it out for me. Is this achievable?

public static SetSqlDbType<T>()
{
    switch(Type.GetTypeCode(typeof(T)))
    {
        case TypeCode.Int64:
            return SqlDbType.BigInt;
        // ... some more cases
        case TypeCode.Object:
        {
            if (typeof(T).GetType().Equals(typeof(byte)))
            {
                return SqlDbType.VarBinary;
            }
        }
    }
}

You can also use `==` instead of `Equals` here. However that will probably not solve the issue, which we don´t know unless you provide what you´ve trie and how it does not work. — MakePeaceGreatAgain, Apr 23 '21 at 08:17
it works just fine for me @HimBromBeere. its just that the `GetType()` thingy made the issue :) — Alvin Quezon, Apr 23 '21 at 08:23

The code:

typeof(T).GetType()

returns you type of Type :)

You can check this much more simplier

typeof(T) == typeof(byte[])

Thank you, I never that that `GetType()` thingy made the issue. – Alvin Quezon Apr 23 '21 at 08:24

You don't need the GetType():

public static bool f<T>(T x) => typeof(T).Equals(typeof(byte[]));
