C#调用命令行执行python脚本,这个办法可以调用python第三方模块和对本地文件进行操作

同步调用:

            string pythonScriptPath = Server.MapPath(@"~\pythonScript");//python脚本所在的目录
            ProcessStartInfo start = new ProcessStartInfo();
            start.FileName = "python";//执行python.exe
            //执行python脚本的命令
            start.Arguments = pythonScriptPath + @"\sen2senScore_v3_console.py ";
            //设置运行python脚本的初始目录 这里注意:如果你的python脚本有文件操作,必须设置初始目录
            start.WorkingDirectory = pythonScriptPath;
            start.UseShellExecute = false;
            start.CreateNoWindow = true;
            start.RedirectStandardOutput = true;
            start.RedirectStandardError = true;
            using (Process process = Process.Start(start))
            {
                using (StreamReader reader = process.StandardOutput)
                {
                    string line = reader.ReadLine();//每次读取一行命令行打印的信息
                }
            }

异步调用:

            string pythonScriptPath = Server.MapPath(@"~\pythonScript");//python脚本所在的目录
            ProcessStartInfo start = new ProcessStartInfo();
            start.FileName = "python";//执行python.exe
            //执行python脚本的命令
            start.Arguments = pythonScriptPath + @"\sen2senScore_v3_console.py ";
            //设置运行python脚本的初始目录 这里注意:如果你的python脚本有文件操作,必须设置初始目录
            start.WorkingDirectory = pythonScriptPath;
            start.UseShellExecute = false;
            start.CreateNoWindow = true;
            start.RedirectStandardOutput = true;
            start.RedirectStandardError = true;
            using (Process process = Process.Start(start))
            {
            	// 异步获取命令行内容
                process.BeginOutputReadLine();
                // 为异步获取订阅事件
                process.OutputDataReceived += new DataReceivedEventHandler((sender, e) =>
                   {
                       v.message = e.Data;//e.Data 就是命令行打印的最后一行信息
                   });
            }
