I have a code that looks like this: using (DC dc = new DC()) { f(dc.obj, a); } void f(DC dc, int a) { ... dc.obj = a; } It doesnt work - complains about object reference and non-static fields. This is a console application, so it has Main() function. How should I make it work? I tried adding references as it asked: I ha...
What is the difference between the following two snippets of code: using (Object o = new Object()) { // Do something } and { Object o = new Object(); // Do something } I have started using using a lot more but I am curious as to what the actually benefits are as compared to scoping objects. Edit: Useful tidbits I took ...
I understand the point of "using" is to guarantee that the Dispose method of the object will be called. But how should an exception within a "using" statement be handled? If there is an exception, I need to wrap my "using" statement in a try catch. For example: Lets say there is an exception created in the creation of the object insi...

Hey guys, I have a question related to choosing an application programmatically when shown the dialog "Complete Action Using" in Android.

I wrote the code below in order to explain my issue. If I comment the line 11 (with the keyword "using"), the compiler does not compile the file and display this error: invalid conversion from 'char' to 'const char*'. It seems to do not see the method void action(char) of Parent class in Son class. Why the compiler behaves this way? Or h...
I just want to verify something. I believe it is likely that if I apply the using command to a SqlDataReader, that it will both close the data reader and dispose of it. For example: Using sdr As SqlDataReader = cm.ExecuteReader() Dim someInt As Integer = sdr.GetInt32(0) 'other details and actions End Using Will that close the ...

In my public class I expose methods which access the datacontext class and convert the data to my own object model classes using linq. In my public class...

"using" statements FTW. He indicates that I need to wrap these Web sessions in "using" stateme...

Hi, I am creating a project that requires the System.ServiceModel.Web.dll. I have added a reference by right-clicking the reference "folder" in the project explorer. A search of the system shows System.ServiceModel.Web.dll in different directories: Program Files(x86), x64, GAC, etc. It doesn't seem to matter which one I pick, as I al...
