【问题标题】：Launch Minecraft 1.8.3 with C#使用 C# 启动 Minecraft 1.8.3

【问题描述】：

我目前正在尝试为我的服务器制作一个 Minecraft 启动器。但是由于某种原因它不会启动。这是我使用的代码。有人可以检查我做错了什么吗？

string installPath = GetJavaInstallationPath();
string filePath = System.IO.Path.Combine(installPath, "bin\\Javaw.exe");

Environment.SetEnvironmentVariable("APPDATA", "C:\\SCO\\");

Process process = new Process();
ProcessStartInfo info = new ProcessStartInfo();
string dir = @"C:\SCO\.minecraft\versions\";
info.FileName = filePath;
info.CreateNoWindow = true;
info.Arguments = "-cp \"" + dir + "1.8.3.jar;" + dir + "lwjgl.jar;" + dir + "lwjgl_util.jar;" + dir + "jinput.jar;\" ";
info.Arguments += "\"-Djava.library.path=" + dir + "natives\" -Xmx1024M -Xms512M net.minecraft.client.main.Main " + username + " " + session;
process.StartInfo = info;
process.Start();

【问题讨论】：

您缺少游戏的大量库和参数。您应该查看版本 JSON（例如，%APPDATA%\.minecraft\versions\1.8.3\1.8.3.json）以获取有关参数结构和库列表是什么的更多信息（理想情况下，您应该从版本 JSON 生成库列表和参数；然后您可以启动所有版本）。

【解决方案1】：

必须试试这个：info.CreateNoWindow = true;到 info.CreateNoWindow = false;

或者重新检查参数，必须是Java路径有效

【讨论】：

我检查了java路径，参数正确。更改 CreateNoWindow 也没有解决问题。您还有其他解决方案吗？
你能告诉我详细的错误（或日志或消息）吗？
我找不到任何东西。该程序不会崩溃它只是什么都不做。

【解决方案2】：

试试这个代码，它对我有用

private void StartMinecraft(string username, string accessToken, string uuid, string gameVersion)
    {
        ProcessStartInfo minecraft = new ProcessStartInfo
        {
            FileName = GetJavaInstallationPath() + @"\bin\javaw.exe",
            CreateNoWindow = false,
            Arguments = " -XX:+UseConcMarkSweepGC -XX:-UseAdaptiveSizePolicy -XX:+CMSParallelRemarkEnabled -XX:+ParallelRefProcEnabled -XX:+CMSClassUnloadingEnabled -XX:+UseCMSInitiatingOccupancyOnly
