InvokeMember不理解？誰能解釋一下 - .NET技術 - C#

.net - C#  Invoke a method with [Type].InvokeMember() in a separate Thread - Stack Overflow

Listing 6 (C#): Dynamic access methods in the ComUtils class

public static object GetProperty(object loObject,

                                 string lcProperty)   {

    return loObject.GetType().InvokeMember(lcProperty,

            BindingFlags.GetProperty,null,loObject,null);

}

public static object SetProperty(object loObject,

          string lcProperty,params object[] loValue)  {

return loObject.GetType().InvokeMember(lcProperty,

          BindingFlags.SetProperty,null,loObject,loValue);

}

public static object CallMethod(object loObject,

        string lcMethod, params object[] loParams)  {

return loObject.GetType().InvokeMember(lcMethod,

       BindingFlags.InvokeMethod,null,loObject,loParams);

}

With this method we can now return the property value as:

public string ReturnCustomer(object loObject)  {  

//*** loObject is passed from VFP – retrieve Company field and return

return (string) ComUtils.GetProperty(loObject,"Company");

}

If you have to return multiple object levels (ie. loObject.oData.Company) you have to drill into each object individually. For example:

public string CallAndReturnCustomer(object loObject)  {  

bool llResult = (bool) ComUtils.CallMethod(loObject,"Load",4)

Object loData = ComUtils.GetProperty(loObject,"oData")

return (string) ComUtils.GetProperty(loData,"Company");
