i have massage error" a property or indexer may not be passed to an out or ref paramenter"how can i do ..

regards,
dede

Is it possible for you to pass the Array over and do the for loop in MyMethod ?

myMethod can't change cause i get it from DLL windows,,

dedex,
you can't pass properteis or indexers to a ref parameter(however you can pass readonly properties),
if you set myArrayList[j] to a new object(ar) after you come out from the method,compiler can't assign new object(as type of Arraylist) to myArrayList[j] because its refrence is changed to a ArrayList Object,so C# compiler doesn't let this operation,
there is a solution for this explained here.

and its solution was,(in this way you can make sure the reference(on stack) to your indexer would not be erased)
just out of my curiosity,can you tell which windows function you were calling?
