Set the value of one COM object member variable failed

[jos]

Hi,all
I wrote a C# project ,in this project , when I create the COM object ,it turns out no error , When I try to get the value of the object's member variable ,it can return the value successfully,but when I try to set the value of the object's member variable,it throws out a "unknown error"!

Could anybody tell me why?

jos,

Is it an exception? If so, what is the type of the exception? Can you show some sample code? Also, are you sure that the property isn't read-only?

Yes, it is not readonly, some other projects also use the COM component, they can set the value of object's member variable.
