Viewing return code in debugger when the value is not assigned to a variable

In case of the following code:

da.Fill(ds)

Is it possible to view the return code from the Fill method in the Visual Studio debugger?

If the following is the case:

rc = da.Fill(ds)

then it's not a problem, as the variable rc g开发者_高级运维ets the value assigned, but there are cases when I can't modify the code and re-build.
