Compiler Error CS1959
'name' is of type 'type'. The type specified in a constant declaration must be sbyte, byte, short, ushort, int, uint, long, ulong, char, float, double, decimal, bool, string, an enum-type, or a reference-type.
The types permitted in a const declaration are limited to those described in this message.
To correct this error
- Declare the constant with an allowed type.
Example
The following code produces CS1959 because null
is not a type.
// cs1959.cs
class Program
{
static void Test<T>() where T : class
{
const T x = null; // CS1959
}
}
