传递MATLAB方法作为.NET对象的委托 [英] Passing MATLAB methods as delegates to .NET Object

问题描述

目前我有一个使用.NET库的MATLAB项目。在Matlab中，我阅读了.dll并实例化了一个我开发的.NET对象，并将数据传递给它和/或从它传递：

  NET.addAssembly（'myLibrary.dll'）; 
 myNetObj = myNamespace.MyClass（）; 
 myNetObj.DoWork（someMatlabVariable）; 
  

遵循MATLAB文档（参见这里）我可以将变量传递给我的.NET函数，但是我想让我的.NET代码调用matlab方法/回调。文档清楚地定义了如何使用.NET代理MATLAB到.NET代理（请参阅这里）。

是否可以传递（指向）一个MATLAB函数作为.NET代理或Action，所以我可以从我的.NET对象调用回调？

解决方案

我发现如何将Matlab函数句柄传递给c＃中的代表。答案被埋在 MATLAB .NET文档中。 p>

在.NET / C＃代码中：

 命名空间SomeNamespace {
 //使用适当的输入参数和返回类型创建代理
 public Delegate void SomeDelegateType（）; 
 
 public class SomeClass {
 //为Matlab创建一个赋值给
 public SomeDelegateType SomeDelegate; 
 ... 
} 
} 
  

在Matlab中： / p>

  //％Instantiate .NET对象
 classInstance = SomeNamespace.SomeClass（）; 
 //％将MATLAB函数句柄分配给.NET Delegate 
 classInstance.SomeDelegate = SomeNamespace.SomeDelegateType（@SomeMatlabMethod）; 
 
函数SomeMatlabMethod（）
 ... 
 end 
  

现在，当.NET代码调用 SomeDelegate（）它将调用Matlab函数 SomeMatlabMethod（）句柄传递

Currently I have a MATLAB project using a .NET library. In Matlab I read in the .dll and instantiate a .NET object that I developed, and pass data to and from it:

NET.addAssembly('myLibrary.dll');
myNetObj = myNamespace.MyClass();
myNetObj.DoWork(someMatlabVariable);

Following the MATLAB documentation (See here) I can pass variables to my .NET functions, but I would like to have my .NET code call matlab methods/callbacks. The documentation clearly defines how to use .NET delegates MATLAB to .NET Delegates (See here).

Is it possible to pass (point to) a MATLAB function as a .NET Delegate or Action, so I can call the callback from my .NET object?

解决方案

I found how to pass Matlab function handles to delegates in c#. The answer is buried in the MATLAB .NET Documentation.

In .NET/C# code:

namespace SomeNamespace{
   // Create Delegate with appropriate input parameters and return types
   public Delegate void SomeDelegateType();

   public class SomeClass{
      // Create a Delegate for Matlab to assign to
      public SomeDelegateType SomeDelegate;
      ...
   }
}

In Matlab:

// % Instantiate .NET object    
classInstance = SomeNamespace.SomeClass();
// % Assign matlab function handle to .NET Delegate
classInstance.SomeDelegate = SomeNamespace.SomeDelegateType(@SomeMatlabMethod);

function SomeMatlabMethod()
   ...
end

Now when the .NET code calls SomeDelegate() it will call the Matlab function SomeMatlabMethod() handle passed to it.
