我安装了单声道和 .net 核心，我正在通过单声道运行它。

有什么建议吗？ （如果可能的话，我想坚持使用 discord.net）

Answer 1

如文档 (https://docs.stillu.cc/guides/getting_started/installing.html) 中所示，无法使用 Mono 运行 Discord.Net。

我建议你切换到 .NET Core。当您现在编译代码时，它将输出一个 .dll 文件（如果 3.1+，则为常规 .exe）

在您的发行版上下载 .NET Core 运行时：https://docs.microsoft.com/en-us/dotnet/core/install/linux

安装后，您应该能够在终端中使用以下命令运行 .dll 文件： dotnet <path_to_dll>

Answer 2

根据文档，它不支持单声道

在另行通知之前，不支持将此库与 Mono 一起使用。众所周知，该库的 WebSockets 实现存在问题，并且可能会在启动时使应用程序崩溃。 https://docs.stillu.cc/guides/getting_started/installing.html?tabs=vs-install%2Ccore2-1

如果你以.net core为目标，它在linux上运行得非常好，因为d.net以.net standard为目标

Answer 3

由于缺少上下文，我将假设您使用 .Net Framework 构建应用程序，我建议您切换到 .Net Core。

之后如 Solarcloud 所述，确保您在 Linux 机器上安装了 Dotnet Core，然后您可以在构建后通过 dotnet MyApplication.dll 简单地运行它，导航到文件夹等。

Answer 4

我只是想尝试一下解决方案，因为我没有看到您提到您在 linux 上安装了 dotnet core。这是一个指南，其中包含一个清单，可按照您的步骤确保其正常工作。 Discord.net 似乎在 .net 核心中。

如果之后仍然失败，请尝试在您的 linux 服务器上运行其他 .net 核心应用程序，看看它们是否有效。我希望这有帮助！
