    Trophy Points:
    I want to create a rsa key in c# and export the container. I am having difficulty. I create container like this:
    CspParameters cspParams = new CspParameters();
    cspParams.KeyContainerName = "XML_ENC_RSA_KEY";The msdn example says I can export the container with this syntax:
    aspnet_regiis -pa "XML_ENC_RSA_KEY" "NT AUTHORITY\NETWORK SERVICE". This does not work on my XP Host PC. I belive this is applicable for Windows 2003 Server.
    1) So what is the correct syntax for exporting rsa key container from XP host?

    Also to get aspnet_regiis.exe path I did something like this:
    string winPath = Environment.GetEnvironmentVariable("windir");
    string fullPath = winPath + @"\Microsoft.NET\Framework\v2.0.50727" + @"\aspnet_regiis.exe";But this path may be different for each host, based on the .NET verison installation.
    2) Is there a way to get the aspnet_regiis.exe path from registry or a environment varaible?

    Once I get the path to aspnet_regiis.exe I want to invokve it from c# like this.
    3) Is this code correct?
    ProcessStartInfo startInfo = new ProcessStartInfo(fullPath);
    startInfo.WindowStyle = ProcessWindowStyle.Hidden;
    startInfo.UseShellExecute = false;
    startInfo.RedirectStandardOutput = true;
    startInfo.RedirectStandardError = true;

    System.Diagnostics.Process process = new System.Diagnostics.Process();
    startInfo.Arguments = args;
    process.StartInfo = startInfo;
    process.WaitForExit();Can someone please help me?
