Passing Parameters to Process File

Hi,

I am making application in C#, Windows Application.

I have to call .Net2003 application by sending some parameters

I am doing as below, but I am not able open my application when I send the parameter. But If I send the parameters it says  that

The system cannot find the file specified

I have to pass the below string to the Process

string strIs =" /strsiteurl="+strDestinationURL+" /strsitename="+siteDetails[0]+" /strsitecode="+siteDetails[0]+" /strsitelanguage="+siteDetails[3]+" /strconn="+new DbConnection().strSourceCon+" /strxmlPath="+ConfigurationSettings.AppSettings["SiteXMLPath"].ToString();


try
{
      System.Diagnostics.Process FProcess =
          new System.Diagnostics.Process();
      FProcess.StartInfo.FileName = Application.StartupPath + @"\Decrypt\vb_passwordDcrypt.exe" + strIs;
      
      /*
            But if I uncomment this line then I am able to open my application
      */
      
      //FProcess.StartInfo.FileName = Application.StartupPath + @"\Decrypt\vb_passwordDcrypt.exe";
      FProcess.Start();
      FProcess,pa
      FProcess.SynchronizingObject = this;
      FProcess.Exited += new System.EventHandler(this.FProcess_Exited);
}
catch (Exception ex)
{
      string str = ex.Message.ToString();
}    



From quick watch when I see the text in

Application.StartupPath + @"\Decrypt\vb_passwordDcrypt.exe" + strIs

I get

"C:\\vb\\DotNet2005\\EnetDatabaseMigration\\EnetDatabaseMigration\\bin\\Debug\\Decrypt\\vb_passwordDcrypt.exe /strsiteurl=www.visitbritain.gr /strsitename=el-GR /strsitecode=el-GR /strsitelanguage=Greek /strconn=Data Source=B025765;Initial Catalog=ENET_20NOV_NEW;User Id=sa;Password=sa; connection timeout=230 /strxmlPath=C:\\vb\\DotNet2005\\EnetDatabaseMigration\\EnetDatabaseMigration\\SiteMapping.xml"

Can anyone help me that how to send parameters to this process

Many Thanks
