run bash command from .NetCore with arguments
提问by holocen
I am trying to run one .NetCore program from another.
我正在尝试从另一个运行一个 .NetCore 程序。
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "sh";
psi.Arguments = "-c dotnet /home/myuser/PublishOutput/myprogram.dll";
psi.UseShellExecute = false;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
Process proc = new Process
{
StartInfo = psi
};
proc.Start();
string error = proc.StandardError.ReadToEnd();
if (!string.IsNullOrEmpty(error))
return "error: " + error;
string output = proc.StandardOutput.ReadToEnd();
proc.WaitForExit();
return output;
As output I get:
作为输出，我得到：
Microsoft .NET Core Shared Framework Host
Version : 1.1.0 Build : 928f77c4bc3f49d892459992fb6e1d5542cb5e86
Usage: dotnet [common-options] [[options] path-to-application]
Common Options: --help Display .NET Core Shared Framework Host help. --version Display .NET Core Shared Framework Host version.
Options: --fx-version Version of the installed Shared Framework to use to run the application.
--additionalprobingpath Path containing probing policy and assemblies to probe for.Path to Application: The path to a .NET Core managed application, dll or exe file to execute.
If you are debugging the Shared Framework Host, set 'COREHOST_TRACE' to '1' in your environment.
To get started on developing applications for .NET Core, install the SDK from: http://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
Microsoft .NET Core 共享框架主机
版本：1.1.0 内部版本：928f77c4bc3f49d892459992fb6e1d5542cb5e86
用法：dotnet [common-options] [[options] path-to-application]
常用选项：--help 显示 .NET Core 共享框架主机帮助。--version 显示 .NET Core 共享框架主机版本。
选项：--fx-version 用于运行应用程序的已安装共享框架的版本。
--additionalprobingpath 包含要探测的探测策略和程序集的路径。应用程序路径：要执行的 .NET Core 托管应用程序、dll 或 exe 文件的路径。
如果您正在调试共享框架主机，请在您的环境中将“COREHOST_TRACE”设置为“1”。
要开始为 .NET Core 开发应用程序，请从以下位置安装 SDK：http: //go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
So I seems exacly like run command dotnetwith no dll path argument.
所以我看起来很像没有 dll 路径参数的运行命令dotnet。

You need to escape the argument to -cso that it is one single argument:
您需要将参数转义-c为一个参数：
psi.Arguments = "-c \"dotnet /home/myuser/PublishOutput/myprogram.dll\"";
