Assign a string value to a property of type Enum which has the corresponding string value as an enumerable const C#

I have the following enum:

public enum PageIdsOptions
    {
        PageID_News = 1,
        PageID_Signup = 2,
        PageID_AffiliateSignup = 3,
        PageID_Cashier = 4,
        PageID_Promotions = 5
    }

and the following property:

public PageIdsOptions Hint { get; set; }

I recieved a string with this value:

string hintValue = "PageID_Signup";

And I want to assign the value of hintValue to the property Hint:

Hint = hintValue;

so that Hint will be equal to

Hint = PageIdsOptions.PageID_Signup;

How can this be done? Any help will be greatly appreciated! Thank You!

Use Enum.Parse method, (this will throw an exception if hintValue contains any invalid value)

Hint = (PageIdsOptions) Enum.Parse(typeof(PageIdsOptions), hintValue);

You can also use Enum.TryParse, (this will return a boolean if the parsing is successful or not, but no exception will be thrown)

PageIdsOptions Hint;

 if (Enum.TryParse(hintValue, out Hint))
    {
         //Parsed successfully
     }
 else
     {
        // Parsing failed
     }

how about

if (!Enum.TryParse(hintValue, out Hint))
{
    // throw an exception because hintValue did not parse.
}

try
{
    var value = Enum.Parse(typeof(PageIdsOptions), hintValue);
}
catch(ArgumentException e)
{
   //todo
}
