How to Convert int to enum in C#

 

Convert int to enum in C#

In C#, an enumeration (enum) is a set of named values, which are treated as a distinct type. Enums are used to define a collection of related values, and they provide a convenient way to work with sets of constant values. Converting an int to an enum in C# is a common task, and in this article, we will cover several ways to do it.

What is an enum in C#?

In C#, an enum is a value type that represents a set of named constants. Enums are used to define a collection of related values, and they provide a convenient way to work with sets of constant values. Enums are often used to define the state of an application or a system, such as the status of a transaction or the state of a game.

Converting an int to an enum in C#

In C#, you can convert an int to an enum in several ways. Here are some of the most common methods:

1. Using the Enum.Parse() method :

The Enum.Parse() method is a built-in C# method that converts a string representation of an enum to its corresponding value. You can use this method to convert an int to an enum by first converting the int to a string and then calling the Enum.Parse() method. Here is an example:

int value = 1;

MyEnum myEnum = (MyEnum)Enum.Parse(typeof(MyEnum), value.ToString());

In this example, we define an int variable named value and a MyEnum variable named myEnum. We then use the Enum.Parse() method to convert the int value to a string and then to a MyEnum value.

2. Using the Enum.ToObject() method

The Enum.ToObject() method is another built-in C# method that can be used to convert an int to an enum. Here is an example:

int value = 1;

MyEnum myEnum = (MyEnum)Enum.ToObject(typeof(MyEnum), value);

In this example, we define an int variable named value and a MyEnum variable named myEnum. We then use the Enum.ToObject() method to convert the int value to a MyEnum value.

3. Using a switch statement

Another way to convert an int to an enum is to use a switch statement. Here is an example:

int value = 1;

MyEnum myEnum;

switch (value)

{

    case 0:

        myEnum = MyEnum.Value0;

        break;

    case 1:

        myEnum = MyEnum.Value1;

        break;

    default:

        myEnum = MyEnum.Value2;

        break;

}

In this example, we define an int variable named value and a MyEnum variable named myEnum. We then use a switch statement to convert the int value to a MyEnum value.

Converting an int to an enum in C# is a common task, and there are several ways to do it. You can use the Enum.Parse() method or the Enum.ToObject() method, or you can use a switch statement. No matter which method you choose, make sure to test your code thoroughly to ensure that the conversion is working correctly.
