                  本文介绍了将 IronPython 方法分配给 C# 委托的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着跟版网的小编来一起学习吧!

                  问题描述

                  我有一个 C# 类,看起来有点像:

                  I have a C# class that looks a little like:

                  public class MyClass
                  {
                      private Func<IDataCource, object> processMethod = (ds) =>
                                                                            {
                                                                              //default method for the class
                                                                            }
                  
                      public Func<IDataCource, object> ProcessMethod
                      {
                          get{ return processMethod; }
                          set{ processMethod = value; }
                      }
                  
                      /* Other details elided */
                  }
                  

                  我有一个 IronPython 脚本,它可以在看起来像这样的应用程序中运行

                  And I have an IronPython script that gets run in the application that looks like

                  from MyApp import myObj #instance of MyClass
                  
                  def OtherMethod(ds):
                      if ds.Data.Length > 0 :
                          quot = sum(ds.Data.Real)/sum(ds.Data.Imag)
                          return quot
                      return 0.0
                  
                  myObj.ProcessMethod = OtherMethod
                  

                  但是当 ProcessMethod 被调用时(在 IronPython 之外),在这个赋值之后,默认的方法就会运行.

                  But when ProcessMethod gets called (outside of IronPython), after this assignment, the default method is run.

                  我知道脚本正在运行,因为脚本的其他部分有效.

                  I know the script is run because other parts of the script work.

                  我应该怎么做?

                  推荐答案

                  我做了一些进一步的谷歌搜索,发现了一个关于 IronPython 黑暗角落的页面:http://www.voidspace.org.uk/ironpython/dark-corners.shtml

                  I did some further Googling and found a page about the darker corners of IronPython: http://www.voidspace.org.uk/ironpython/dark-corners.shtml

                  我应该做的是:

                  from MyApp import myObj #instance of MyClass
                  import clr
                  clr.AddReference('System.Core')
                  from System import Func
                  
                  def OtherMethod(ds):
                      if ds.Data.Length > 0 :
                          quot = sum(ds.Data.Real)/sum(ds.Data.Imag)
                          return quot
                      return 0.0
                  
                  myObj.ProcessMethod = Func[IDataSource, object](OtherMethod)
