How to Convert a int to an enum in C#

To convert an int to an enum in C#, you can use the Enum.ToObject() method or a direct cast. Here's an example using both approaches:

using System;

public enum Colors
{
    Red,
    Green,
    Blue,
    Yellow,
    Orange
}

class Program
{
    static void Main(string[] args)
    {
        int intValue = 2;

        // Using Enum.ToObject
        Colors color1 = (Colors)Enum.ToObject(typeof(Colors), intValue);
        Console.WriteLine($"Using Enum.ToObject: {color1}");

        // Using direct cast
        Colors color2 = (Colors)intValue;
        Console.WriteLine($"Using direct cast: {color2}");
    }
}

In this example, the Colors enum has five members. The intValue variable is set to 2. The Enum.ToObject() method is called with the typeof(Colors) argument and the intValue to convert the int value to a Colors enum member. The direct cast approach simply casts the intValue to the Colors enum type.

Both approaches will output:

Using Enum.ToObject: Blue
Using direct cast: Blue

Keep in mind that when converting an int to an enum, the value should be valid for the enum type. If the value doesn't correspond to a valid enum member, it will still be converted, but the result might not make sense in the context of your application. To check if the integer value is a valid enum member, you can use the Enum.IsDefined() method.

int intValue = 2;
DaysOfWeek day = Enum.ToObject(typeof(DaysOfWeek), intValue) as DaysOfWeek;

Using Enum.IsDefined for int to enum conversion in C#: Checking if an integer value is defined in the enum using Enum.IsDefined before conversion.
```
int intValue = 2;

if (Enum.IsDefined(typeof(DaysOfWeek), intValue))
{
    DaysOfWeek day = (DaysOfWeek)intValue;
}
```

Convert int to enum with TryParse in C#: Using Enum.TryParse to convert an integer to an enum safely.

int intValue = 2;
if (Enum.TryParse(typeof(DaysOfWeek), intValue.ToString(), out DaysOfWeek day))
{
    // Conversion successful
}

```
int intValue = 2;
DaysOfWeek day = (DaysOfWeek)intValue;

Mapping int values to enum in C#: Creating a mapping function to convert int values to an enum.

int intValue = 2;
DaysOfWeek day = MapIntToEnum(intValue);

// ...

private static DaysOfWeek MapIntToEnum(int value)
{
    // Logic to map int to enum
    return (DaysOfWeek)value;
}

C# explicit and implicit casting from int to enum: Demonstrating explicit and implicit casting from int to enum.

int intValue = 2;

// Explicit casting
DaysOfWeek explicitDay = (DaysOfWeek)intValue;

// Implicit casting (with caution)
DaysOfWeek implicitDay = intValue; // Use with caution, may result in unexpected behavior
