c# – 有没有一种很好的方法将结果从外部进程流式传输到Visual Studio输出窗格?
作者:互联网
我在VsPackage中设置了一个自定义输出窗格,类似于以下内容:
///--------------------------------------------------------------------------------
/// <summary>This property gets the custom output pane.</summary>
///--------------------------------------------------------------------------------
private Guid _customPaneGuid = Guid.Empty;
private IVsOutputWindowPane _customPane = null;
private IVsOutputWindowPane customPane
{
get
{
if (_customPane == null)
{
IVsOutputWindow outputWindow = GetService(typeof(SVsOutputWindow)) as IVsOutputWindow;
if (outputWindow != null)
{
// look for existing solution updater pane
if (_customPaneGuid == Guid.Empty || ErrorHandler.Failed(outputWindow.GetPane(ref _customPaneGuid, out _customPane)) || _customPane == null)
{
// create a new solution updater pane
outputWindow.CreatePane(ref _customPaneGuid, "My Output", 1, 1);
if (ErrorHandler.Failed(outputWindow.GetPane(ref _customPaneGuid, out _customPane)) || _customPane == null)
{
// pane could not be created and retrieved, throw exception
throw new Exception("Custom pane could not be created and/or retrieved");
}
}
}
}
if (_customPane != null)
{
_customPane.Activate();
}
return _customPane;
}
}
并使用类似于以下方法的方法将消息发送到此窗格:
///--------------------------------------------------------------------------------
/// <summary>This method displays a message in the output area.</summary>
///
/// <param name="outputTitle">The title for the message.</param>
/// <param name="outputMessage">The message to show.</param>
/// <param name="appendMessage">Flag indicating whether message should be appended to existing message.</param>
///--------------------------------------------------------------------------------
public void ShowOutput(string outputTitle, string outputMessage, bool appendMessage, bool isException)
{
if (appendMessage == false)
{
// clear output pane
CustomPane.Clear();
}
if (outputTitle != string.Empty)
{
// put output title to output pane
CustomPane.OutputString("\r\n" + outputTitle);
}
// put output message to output pane
CustomPane.OutputString("\r\n" + outputMessage);
if (isException == true)
{
// show message box
MessageBox.Show(outputTitle + "\r\n" + outputMessage, outputTitle);
}
}
我有一个外部进程将当前解决方案的诊断结果发送到控制台.它的设置类似于以下内容:
///--------------------------------------------------------------------------------
/// <summary>This method handles clicking on the Run Diagnostics submenu.</summary>
///
/// <param term='inputCommandBarControl'>The control that is source of the click.</param>
/// <param term='handled'>Handled flag.</param>
/// <param term='cancelDefault'>Cancel default flag.</param>
///--------------------------------------------------------------------------------
protected void RunDiagnostics_Click(object inputCommandBarControl, ref bool handled, ref bool cancelDefault)
{
try
{
// set up and execute diagnostics thread
RunDiagnosticsDelegate RunDiagnosticsDelegate = RunDiagnostics;
RunDiagnosticsDelegate.BeginInvoke(RunDiagnosticsCompleted, RunDiagnosticsDelegate);
}
catch (Exception ex)
{
// put exception message in output pane
CustomPane.OutputString(ex.Message);
}
}
protected delegate void RunDiagnosticsDelegate();
///--------------------------------------------------------------------------------
/// <summary>This method launches the diagnostics to review the solution.</summary>
///--------------------------------------------------------------------------------
protected void RunDiagnostics()
{
try
{
// set up diagnostics process
string solutionDir = System.IO.Path.GetDirectoryName(_applicationObject.Solution.FullName);
System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo(@"MyDiagnostics.exe", solutionDir);
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = true;
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
// execute the diagnostics
proc.Start();
// put diagnostics output to output pane
CustomPane.OutputString(proc.StandardOutput.ReadToEnd());
CustomPane.OutputString("Diagnostics run complete.");
}
catch (Exception ex)
{
// put exception message in output pane
CustomPane.OutputString(ex.Message);
}
}
///--------------------------------------------------------------------------------
/// <summary>This method handles completing the run diagnostics thread.</summary>
///
/// <param name="ar">IAsyncResult.</param>
///--------------------------------------------------------------------------------
protected void RunDiagnosticsCompleted(IAsyncResult ar)
{
try
{
if (ar == null) throw new ArgumentNullException("ar");
RunDiagnosticsDelegate RunDiagnosticsDelegate = ar.AsyncState as RunDiagnosticsDelegate;
Trace.Assert(RunDiagnosticsDelegate != null, "Invalid object type");
RunDiagnosticsDelegate.EndInvoke(ar);
}
catch (Exception ex)
{
// put exception message in output pane
CustomPane.OutputString(ex.Message);
}
}
当我从VSPackage启动此外部进程时,我希望将这些结果(间接)流式传输到自定义输出窗格,在诊断工具报告它们时显示消息.有没有一个好方法呢?
解决方法:
显然你必须使用Process.BeginOutputReadLine()方法.可以在这里找到一个例子:System.Diagnostics.Process.BeginOutputReadLine.
