C# – How to convert from PDF to XPS

acrobatcnetpdfxps

I use the following method to print a XPS file with adobe acrobat:

private void GenerateXPS(String filename)
        {
            Process proc = new Process();
            proc.StartInfo.FileName = "AcroRd32.exe";
            proc.StartInfo.Arguments = "/t " + filename + ".pdf" + " " + "\"Microsoft XPS Document Writer\"";
            proc.Start();
        }

But the problem is, the Microsoft XPS Document writer needs a filename where to store the document. Now I'm asked to enter this filename by Adobe Acrobat, but I want to pass this filename as well in the arguments. Or if this is not possible just use the same filename. Is this possible?

If it isn't mandatory that you use acrobat, you might try printing the file directly to the Microsoft XPS Document writer. You can do this without the UI popping up. (see Feng Yuan's blog post for more details)

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);
