Upgrading code from Vb.NET 2003 to 2008 , Narrowing Conversion?
I'm upgrading my vb.net code from 2003 to 2008. I'm getting a narrowing conversion error on the 4th line. Any ideas?
Dim fs As FileStream
Dim sr As StreamReader
Try
fs = New System.IO.FileStream(flXML, System.IO.FileMode.Open, System.IO.FileShare.ReadWrite, FileShare.Read)
sr = New System.IO.StreamReader(fs)
DSet.ReadXml(sr)
sr.Close()
fs.Close()

flXML is just string type, it has the file path to the xml document.
A narrowing conversion is when you convert from one data type to another, and the source datatype is larger than the destination type. Like converting a 64-bit number to a 32-bit number. This should typically produce a compiler warning, but should generally work. It will produce an error at compile time if you've told the compiler to report warnings as errors or at runtime if you try to convert a value that won't fit in the smaller type (say, the source variable has a number larger than will fit in your 32bit destination, but less than the max 64bit value).
What is flXML, and where did it come from? Looking at the various overloads (my system only has .Net 2.0, so there may be some new options in 3.5) it's likely either a String, IntPtr, or SafeFileHandle. I'm guessing an IntPtr, since that would be susceptible to the conversion problem.
