This link offers sample code to infer the schema of an XML file, in VB.NET. One particular line fails in my translation to C#, namely,
Dim schema As XmlSchema = schemaSet.Schemas()(0)
My translation is
XmlSchema schema = schemaSet.Schemas()[0];

I have a line of C# code and can't translate it correctly. 'myString' is a string and 'a' and 'k' are both UInt:a += (uint)(myString[k + 0] + (myString[k + 1] << 8) + (myString[k + 2] << 16) + (myString[k + 3] << 24)); Translators for VB suggest the following but I get "Operator '<<' is not defined for types 'Char' and 'Integer': a += CUInt(myString(k + 0) + (myString(k + 1) << 8) + (myString(k + 2) << 16) + (myString(k + 3) << 24))

I have a hashing method whose operations depend on input to the function. Profiling the program has shown that too much time is spent evaluating this hash method. I want to try changing it into an expression tree, so the inner loop checks can be done once.
Here is a simplified version of the function (I undid some obvious optimizations for the example, and took out any input validation):
Private Function Checksum(ByVal inputValues As IEnumerable(Of UInt32),
ByVal declarations As IEnumerable(Of String),
ByVal statements As IEnumerable(Of String)) As UInt32
Dim variables = New Dictionary(Of Char, UInt32)
[code]....
I want to create a function which takes the declarations and statements and outputs a specialized expression tree representing a function which takes an IEnumerable of UInt32 and returns a UInt32.Follow-Up:I succeeded, and the speed-up was ridiculous (an order of magnitude). The main things I had to learn where:Use Expression.Lambda and Expression.Compile to get a delegate you can actually use.The Expression.Block factory method has a 'variables' parameter you (essentially) use to declare locals.Expression.lambda has 'parameters'.If you call Expression.Parameter twice, you're dealing with two different variables (even if their name is the same)! Store the result for later usage. Same for labels, etc.The result of a BlockExpression is the last expression in the block.

I have this working on VB6 that saves a query in a excel sheet:
[Code]...
The XLSNombre is a variable with the name of the excel file that has been set before. The connection I have in .NET is to SQL server (but is the same). How can I use this code (or..how can I make this code work for .NET) or what is the equivalent of this for .NET? I found some solutions but with inserts of single rows or I have to set the title of the columns, I dont find any "simple" solution to do an "insert into" (like the code I use in VB6).
I came accross the code below in a book. I prefer displaying my data in Winforms instead of the Console which the boook uses but I have little understanding of console codes and how to convert them to Winforms.[code]....

Does anybody know how to ignore a line(s) of code after a line(s) has executed. Let say you have a button1, and two CheckBoxes. By clicking once button1, cheheckbox1 checked. By clicking agin button1, then CheckBox2 checked. You will probably say that I can do that in diferent way, but it isn't the solution of this problem that I want. This is only an example.
