I am trying to convert my EnumerableRowCollection into a DataTable, but I can't see the CopyToDataTable method. The enm.CopyToDataTable() has the blue saw tooth line under it with error saying " 'CopyToDataTable' is not a member of 'System.Data.EnumerableRowCollection' ". I have set a Reference to System.Data, System.Data.Linq, and System.Data.DataSetExtensions. I thought the CopyToDataTable method was part of the System.Data.DataSetExtensions, right? Anyone know why I can't access this method?

I am having a problem with an application I have developed, there seems to be a memory leak that causes the application to crash when it fills up the RAM. I have a process that repeats for each row of a given table, while this process works fine there is one line in particular which converts the results of a linq .tolist which is never disposed of. Since this process is only able to be executed ~200 times before an outofmemory exception occurs.
How can I dispose of the instance of each class to clear this memory in between iterations, or failing this is there a particular area in which I can look further to solve this problem?

I've been reading the MSDN Library and I need to use the StreamReader.Peek Method to check a text file while a I parse it.
When I try to use the Peek Method, I get an error saying , "Peek is not a member of System.IO.Stream."
I don't understand why it is happening because I am following the examples on MSDN, and I even checked other sources and it seems like I am doing everything correct. I am hoping it is just something small that I have missed.
I am also importing System, System.IO, and System.Text.
why the following code
Dim myStrings(My.Settings.test.Count - 1) As String
My.Settings.test.CopyTo(myStrings, 0)
DataGridView1.DataSource = myStrings.Select(Function(s) New With {.Value = s}).tolist
would be giving me grief in an existing app but work fine when i put it a new project starting from scratch. I'm getting the following error:
