Continuous Execution Multiple Functions independently c#

I want to call multiple functions continuously each minute inside a while loop. Even any function execution time takes more than one minute, other functions should not wait for other functions to complete. If I write like the below,

        while (true)
        {
            if(executebinary) BinaryConversion();
            if(emailvalidation) ValidateEmails();

            System.Threading.Thread.Sleep(60000);
        }

any delay in function BinaryConversion() will also delayed execution of function ValidateEmails(). Is there any way to run both functions simultaneously?

You can use Parallel.Invoke if you want them to run in parallel:

while (true)
{

    Parallel.Invoke(BinaryConversion, ValidateEmails);

    System.Threading.Thread.Sleep(1000);
}

Based on your edit a longer example:

namespace CSharp
{
  using System;
  using System.Threading.Tasks;

  class Program
  {
    static void Main()
    {
      bool executebinary = true;
      bool emailvalidation = false;

      while (true)
      {
        Parallel.Invoke(
          () =>
            {
              if (executebinary)
              {
                BinaryConversion();
              }
            },
          () =>
            {
              if (emailvalidation)
              {
                ValidateEmails();
              }
            });

        System.Threading.Thread.Sleep(1000);
      }
    }

    private static void ValidateEmails()
    {

    }

    private static void BinaryConversion()
    {

    }
  }
}

Based on your comment both running simultanously without interference from the other:

namespace CSharp
{
  using System;
  using System.Threading.Tasks;

  class Program
  {
    static void Main()
    {
      bool executebinary = true;
      bool emailvalidation = false;

      Parallel.Invoke(
        () =>
          {
            while(true) if (executebinary) BinaryConversion();
          },
        () =>
          {
            while(true) if (emailvalidation) ValidateEmails();
          });
      }
    }

    private static void ValidateEmails()
    {

    }

    private static void BinaryConversion()
    {

    }
  }
}

There are multiple ways: If you are using C# 5 then two ways:

if you create a methods using async, you can

Timer: Kick off a timer with 1 minute interval and then call the methods using async & await: http://msdn.microsoft.com/en-us/library/vstudio/hh191443.aspx or As mentioned by nvoigt

In this case you don;t need Thread.Sleep.

If you are using a earlier versions:

You can still use timer and then create a delegate for these methods and then invoke them asynchronously:

http://msdn.microsoft.com/en-us/magazine/cc301332.aspx

The reason you might want to avoid thread.sleep is if its a UI application, it would block the thread of a minute, which you want to avoid.
