Convert Code to C# ?

[MrGTI]

I know how to convert code in C# to VB.NET. But in this one small instance, i want to convert code from VB.NET into C#.

Does anyone know of a utility/webpage that does this? It's not a lot of code. Only maybe 10 lines or so.

Post the code here, we can all chip in

I can figure out the declaration of the string variables, the message box, the changes to the try-catch, and even the trailing semi colan.

But it's the XML objects and System variables i don't know how to change:

Dim sAppPath As String = System.Environment.CurrentDirectory
        Dim sFilename As String = sAppPath & "SampleFile.XML"
        Dim oXML As System.Xml.XmlDataDocument = New XmlDataDocument()
        oXML.Load(sFilename)
        Dim sTmp As String = ""
        Try
            sTmp = oXML.SelectSingleNode("//AppUpdateURL").InnerText
        Catch
            'An error here might indicate that there is no node with that given name
        End Try
        MsgBox("the URL is: " & sTmp)
        oXML = Nothing

That's why i was looking for a way to convert it; so i can see what the different syntax is.

example
Dim oXML As System.Xml.XmlDataDocument = New XmlDataDocument()



=

System.Xml.XmlDataDocument oXML = new XmlDataDocument();

This is the converted version . It should works fine .

public void C_Code(){
		string sAppPath =System.Environment.CurrentDirectory;
		string sFilename =sAppPath + "SampleFile.XML";
		System.Xml.XmlDataDocument oXML = new System.Xml.XmlDataDocument();
		oXML.Load(sFilename);
		string sTmp =null;

					try {
						sTmp = oXML.SelectSingleNode("//AppUpdateURL").InnerText;
					}
					catch (System.Exception x) {
						MessageBox.Show (x.Message);
					}
		MessageBox.Show ("the URL is: " + sTmp);
		oXML = null;

}

I had to add a \\ before the name of the file because C# doesn't have the trailing backslash like VB.NET does. Other than that, all that code helps. It works.

I have found a major flaw in my code. - The program crashes hard if the XML is NOT there.

In VB.NET i'd just use the Dir function to verify that the file/path was valid. I'll have to see if there is a translation for the Dir function in C#.

Actually,... if i just re-arrange the order of the items to have the .Load inside the TryCatch, i can avoid the error.

So that works fine then. Thanks.

Here is a trick you can use to eliminate the \\'s
You way now:
("\\AppUpdateURL")
Another way you can do it:
(@"\AppUpdateURL")

The @ sign in front of a string makes C# count it as a literal string, and tells it that there is no backslash constants in the string.

[MrGTI]

I was wondering what that was for. I'd seen it in a few examples, and i couldn't understand what it did.

Thanks!
