          richTextBox1.Text = output;

      }

推荐答案

您可能必须提供java.exe文件和Addition.jar文件的完整路径.

You probably have to provide the full path to the java.exe file and the Addition.jar file.

在Ron siad的基础上，您正在开始该过程，然后立即尝试读取可能尚未写入的流，因此您一无所获.

在Start调用之后，请在尝试读取这些流之前，在Process对象上调用WaitForExit.

On top of what Ron siad, you''re starting the process and then immediately trying to read streams that probably haven''t been writen to yet, so, you get back nothing.

After the Start call, call WaitForExit on the Process object before you try to read those streams.
