Compiler Error CS0031
Constant value 'value' cannot be converted to a 'type'. (use 'unchecked' syntax to override)
An attempt was made to assign a value to a variable whose type cannot store the value. For more information, see Types (C# Programming Guide).
The following sample generates CS0031 in both checked and unchecked contexts:
// CS0031.cs
namespace CS0031
{
public class a
{
public static void Main()
{
int num = (int)2147483648M; //CS0031
// Try using a larger numeric type instead:
// long num = (long)2147483648M; //CS0031
const decimal d = -10M; // Decimal literal
unchecked
{
const byte b = (byte)d; // CS0031
// For small values try using a signed byte instead:
// const sbyte b = (sbyte)d;
}
}
}
}
