What is the use and general practical use of using Tuples in .NET 4.0?

Question

I had read about Tuples, which was presented at the output of the new .NET Framework features, and yet I wonder how it can be useful in enterprise applications of the real world.

Can anyone give me a brief explanation along with a simple real-world code example?

Thank! =)

Answer 1

Tuples are currently not as significant in C # because there is no clear syntax for them. However, the concept is very common in functional languages ​​such as F # (new to .NET 4.0).

:

return new Tuple<int, string, char>(1, "some string", 10.00);

public class ReturnMany
{
   public int intValue { get; set; }
   public string strValue { get; set; }
   public decimal decValue { get; set; }
}

return new ReturnMany() { intValue = 1, strValue = "some string", decValue = 10.00 }

Answer 4

Tuples in .NET are immutable, so they are also an easy way to pass a bunch of values ​​around threads. I am currently using tuples with Retlang, and they are great for use with this type of library.
