If you want to execute an existing Microsoft SQL Server Agent Job in C# you an use the following function:

The function uses SQL authentication to connect to the Microsoft SQL Server instance.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Smo.Agent;
using Microsoft.SqlServer.Management.Common;
using System.Data;

public override void Execute()
    {
      Server server = new Server(@"MyServer\MyInstanceName");
      try
      {
        server.ConnectionContext.LoginSecure = false;
        server.ConnectionContext.Login = "MyName";
        server.ConnectionContext.Password = "MyPassword";
        server.ConnectionContext.Connect();
        Job job = server.JobServer.Jobs[Name];
        job.Start();
      }
      finally
      {
        if (server.ConnectionContext.IsOpen)
        {
          server.ConnectionContext.Disconnect();
        }

}
}

Add this after the above method to have the Job wait until it’s done

Thread.Sleep(5000);
job.Refresh();
while(job.CurrentRunStatus != JobExecutionStatus.Idle)
{
Thread.Sleep(5000);
job.Refresh();
}
