In this short post, I show How to cast int to enum in C#. We have used an enumeration type (or enum type) in our day to day programming. Enum is a value type defined by a set of named constants of the underlying integral numeric type. To define an enumeration type, we used the enum keyword and specified the names of enum members as shown in below example.

public enum OrderStatus
{
Received = 1,
InProgress = 2,
Processed = 3,
Shipped = 4
}

How to convert int to enum ?

Let’s take an example to demonstrate real time scenario. Consider we have a field that represents order status for a given product order.

public OrderStatus Status {get; set;}

OrderStatus is the enum that is defined with various status. E.g. Received, InProgress, Processed and Shipped.

Say you need to convert int or string to enum, it is easy to do so.

OrderStatus variableName = (OrderStatus)Enum.Parse(typeof(OrderStatus), yourStringVariable);

Yes, it is that easy to cast int to enum type.

Validate enum property in model

Say, your enum property needs to be validated in a given model, simple use the EnumDataType as shown below.

[Required]
[EnumDataType(typeof(OrderStatus), ErrorMessage = "Provide initial order status")]
public OrderStatus Status { get; set; }
