C# Process Start Stuck

2018-04-17 05:13 Bing Feng imported from Stackoverflow

I wrote a simple TCP Server application, when the program gets the request it will call an exe file to do something. The application works fine on my PC.

But when I run on another PC the thread will stuck because it stuck in process start, so I checked the task manager whether the exe file did run. and it really work.

I have no idea how to solve it.

Here is my code:

System.Diagnostics.Process process = new System.Diagnostics.Process();
string path = System.Environment.CurrentDirectory;
process.StartInfo.WorkingDirectory = path;
process.StartInfo.FileName = "FileTransferTool\\FileTransfer.exe";
process.StartInfo.Arguments = argument;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.CreateNoWindow = false;

process.Start();  // the thread stuck here

I print out the message, it shows

System.ComponentModel.Win32Exception (0x80004005):

The system cannot find the file specified at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startIn fo) at System.Diagnostics.Process.Start() at ClassPackage.DsUploadFiletoNC.Start(Object[] param)

    I have solved this problem by adding another process to call cmd.exe on the top of the main program, the code shown as below :

    And the program will run as Administrator, but I don't know why

    static void Main(string[] args)
    {
        System.Diagnostics.Process process = new System.Diagnostics.Process();
        string path = System.Environment.CurrentDirectory;
        process.StartInfo.WorkingDirectory = @"C:\Windows\System32";

        process.StartInfo.FileName = "cmd.exe";
        //process.StartInfo.FileName = "FileTransferTool\\circle.txt";

        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardInput = true;
        process.StartInfo.RedirectStandardInput = true;
        //process.StartInfo.CreateNoWindow = false;
        process.Start();

        using (TCPServer server = new TCPServer())
        {
            server.Start();
            Console.WriteLine("Socket Server Start...");
            Console.ReadKey(true);
        }
    }

  • How to reorder Items after looping HttpRequests

    I have the following problem (using C# in a Xamarin / Android app):

    1. Every second the UI Thread calls a DoLongTaskAsync function which is awaited and returns a result item.

    2. The duration of the DoLongTaskAsync function can differ, sometimes it lasts 2 seconds, sometimes just 0.5 seconds.

    3. After 30 seconds I wanna put the result items in the same order like the calls that have been done.

    4. I can not pass a variable to the DoLongTaskAsync.

    Whats the best way to solve this?

  • Get PublicKey from KeyStore in Android Xamarin App

    I writing Xamarin app an i need modulus and exponent from KeyPair, but i got an issue with PublicKey object. Code below throws an exception:

  • How to add nuget packages to c# project files with nuget.core

    I am trying to upgrade a bunch of old c# projects to consume nuget packages that I have made from old assembly dependencies. I want to write a C# program to update all the csproj files to reference the package.

    I have the code using nuget.core making a dictionary of dependent assemblies to a nuget package. I can iterate over the references in my project file and find the needed nuget package from my repository. 

    var localRepo = PackageRepositoryFactory.Default.CreateRepository(nugetCachePath);
var packages = localRepo.GetPackages();
foreach (var package in packages)
{
   foreach (var assemblyReference in package.AssemblyReferences)
   {
        assemblyToPackage.Add(Path.GetFileNameWithoutExtension(assemblyReference.Name).ToLower(),package);
   }               
}

    I think I need to use Nuget.Core ProjectManager to add the reference to my project file (csproj). 

    <ItemGroup>
    <PackageReference Incluse="KB.MyOldAssemblyPackage">
       <Version>1.0.0</Version>
    </PackageReference>
</ItemGroup>

    What I can't figure out is how to get an instance of ProjectManager or any examples on how to use it to add the nuget reference. I know I could simply inject the xml with an xdocument but since I made the effort to use nuget.core I was hoping to find a solution using it.

    Any help out there?
