How Can I Efficiently Capture External Process Output in .NET?

.NET process output capture: comprehensive guide

External commands or applications need to be processed and captured in the .NET program. This guidelines have deeply discussed the steps and precautions of the high -efficiency promoter process and capturing its standard output (Stdout) in the .NET.

Understand the process of creation

To start the sub -process, please create a Process object and configure its startinfo property. The CreateNDOW logo ensures that the process is running without a console window, while RedirectStandardOutPut allows its output through the StandardOutput property.

Processing output data

When the process is output, the P.outPutDataReceived event will be called. To receive and process this output, create a DataReceiveDeventhandler commission and attach it to the event. In the processing program, use StreamReader to read output and save it in a string or appropriate data structure. Event processing optimization

Asynchronous incident processing ensures that the application can respond even when the output of the child is captured from the child process. By using Process.BeginoutputReadline (), you can start a dedicated thread to process the output data to release the main thread to perform other tasks.

Read the output directly

Although event processing is very useful for real -time monitoring, the simpler method is to read the output directly using p.standardoutputput.readtond (). This method will block until all outputs are received, but this provides a direct method to capture all output at one time.
