How can an int be cast to an enum in C#?
739
Use the Type Casting to Convert an Int to Enum in C# The correct syntax to use type casting is as follows. Copy YourEnum variableName = (YourEnum)yourInt; The program below shows how we can use the type casting to cast an int to enum in C#. We have cast our integer value to enum constant One .
C++ Explicit type conversions Enum conversions static_cast can convert from an integer or floating point type to an enumeration type (whether scoped or unscoped), and vice versa. It can also convert between enumeration types.
The enum can be of any numeric data type such as byte, sbyte, short, ushort, int, uint, long, or ulong. However, an enum cannot be a string type.
You can create Enumeration without casting, it is not required.
From an int:
YourEnum foo = (YourEnum)yourInt; From a string:
YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString); // The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(",")) { throw new InvalidOperationException($"{yourString} is not an underlying value of the YourEnum enumeration.") } Update:
From number you can also
YourEnum foo = (YourEnum)Enum.ToObject(typeof(YourEnum) , yourInt); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
