C# – Cannot implicitly convert type ‘Int’ to ‘T’

cgenerics

I can call Get<int>(Stat); or Get<string>(Name);

But when compiling I get:

Cannot implicitly convert type 'int' to 'T'

and the same thing for string.

public T Get<T>(Stats type) where T : IConvertible
{
    if (typeof(T) == typeof(int))
    {
        int t = Convert.ToInt16(PlayerStats[type]);
        return t;
    }
    if (typeof(T) == typeof(string))
    {
        string t = PlayerStats[type].ToString();
        return t;
    }
}

Best Answer

You should be able to just use Convert.ChangeType() instead of your custom code:

public T Get<T>(Stats type) where T : IConvertible
{
    return (T) Convert.ChangeType(PlayerStats[type], typeof(T));
}

C# – How to calculate someone’s age based on a DateTime type birthday

An easy to understand and simple solution.

// Save today's date.
var today = DateTime.Today;

// Calculate the age.
var age = today.Year - birthdate.Year;

// Go back to the year in which the person was born in case of a leap year
if (birthdate.Date > today.AddYears(-age)) age--;

However, this assumes you are looking for the western idea of the age and not using East Asian reckoning.

C# – How to cast int to enum

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);
