Hi,

I have a problem on C# windows service, its showing an error - The array bounds are invalid

Note - If my dv.Count value is less than or equal to 1000 then its not showing error and works fine, but id dv.Count is more then 1000 then it generate the error....

Here is my code

C#

string[] arg = new string[dv.Count]; // here dv is nothing, just a dataview which contains id and items of product datatable

  for (int xx = 0; xx < dv.Count; xx++)
  {
  arg[xx] = dv[xx]["id"].ToString() + "," + dv[xx]["item"].ToString()
  }

    ServiceController sc = new ServiceController("Service1"); //Here Service1 is my child service name which i want to start from this parent service

  if (sc != null)
  {
  if (sc.Status.ToString().ToLower() == "stopped")
  {
  sc.Start(arg); // Error Occurred Here
  }
  }

Here is the full error details.

System.InvalidOperationException: Cannot start service xxxxx on computer '.'. ---> System.ComponentModel.Win32Exception: The array bounds are invalid<br />
  --- End of inner exception stack trace ---<br />
  at System.ServiceProcess.ServiceController.Start(String[] args)<br />
  at xxxxxx.Service1.Generate(Object sender, ElapsedEventArgs e)

Can someone please help on this...?

I suppose the first question is.. what is dv? How is it declared?

anurag.netdeveloper 13-Nov-13 2:32am

dv is datview...

What is "Service1"? Could you show its start method?

We need the code in sc.Start as the error occurs in it!!!

sc.Start(arg) is just a instance to start the child service - "Service1"...

This Service is my parent service which a invoker for child service....

try this and let us know your problem is solved or not.

C#

string[] arg = new string[dv.Count+1];
for (int xx = 0; xx < dv.Count; xx++)
{
arg[xx] = dv[xx]["id"].ToString() + "," + dv[xx]["item"].ToString()
}

  ServiceController sc = new ServiceController("Service1");
if (sc != null)
{
if (sc.Status.ToString().ToLower() == "stopped")
{
sc.Start(arg); // Error Occurred Here
}
}

This is just a work arround to test the code.

This is what sc.Start(arg); does:

C#

public void Start(string[] args)
{
    // removed code (here) irrelevant to this issue
    IntPtr[] ptrArray = new IntPtr[args.Length];
    int index = 0;
    // removed code (here) irrelevant to this issue (build ptrArray...)
    GCHandle handle = new GCHandle();
    try
    {
        handle = GCHandle.Alloc(ptrArray, GCHandleType.Pinned);
        //This next line is where the trouble is!
        if (!UnsafeNativeMethods.StartService(serviceHandle, args.Length, handle.AddrOfPinnedObject()))
        {
            Exception innerException = CreateSafeWin32Exception();
            throw new InvalidOperationException(Res.GetString("CannotStart", new object[] { this.ServiceName, this.MachineName }), innerException);
        }
    }
    // removed code (here) irrelevant to this issue (misc cleanup...)
}

Considering where the problem appears to be (above), it looks like there's a 1000 element limit on the size of the array of args (OR perhaps a maximum total length of arguments) that can be passed to:

C#

[DllImport("advapi32.dll", CharSet=CharSet.Unicode, SetLastError=true)]
public static extern bool StartService(IntPtr serviceHandle, int argNum, IntPtr argPtrs);

Consider wrapping your code in a try...catch and calling Marshal.GetLastWin32Error to determine exactly what went wrong.
