Convert Array.FindIndex from C# to VB

Question

I have this line in C#:

newline_pos = Array.FindIndex(buffer, offset, bytes, x => (x == NEWLINE));

Really have question in this part x => (x == NEWLINE).

Please help me.

It's called a lambda expression, and you can use it in VB.NET, but the syntax is quite different. — Tim, Dec 26 '14 at 03:44
try this `Dim newline_pos As Integer = Array.FindIndex(buffer, offset, bytes, Function(s) s = NEWLINE);` — prospector, Dec 26 '14 at 03:58
If you want to convert the code from C# to VB, there's plenty of free online converter available. If you want to understand what lambda expression are, you should search for a tutorial. In both case, google will help you. — The_Black_Smurf, Dec 26 '14 at 03:59

@Jearca Using the converter will solve your other question **[here](http://stackoverflow.com/questions/27643644/converting-function-t-to-c-sharp-to-vb-net)**. Dont forget to mark correct answers (the holo tickbox under the voting buttons. – Jeremy Thompson Dec 26 '14 at 04:06
thanks is the correct lambda expression the problem is x is a byte and NEWLINE is a char, so i have a error i need to know if that expression is correct?? `Function(x) x.CompareTo(NEWLINE)` – Jearca Dec 26 '14 at 04:07
VB.Net uses *implicit* casting, it doesn't require *Explicit* casting. So in VB.Net you dont worry about converting the byte to char to test for equality. Only in C# do you have to *explicitly* cast types. – Jeremy Thompson Dec 26 '14 at 04:08
ok, but i have a error and i cant compile, for that i need know if i can use `Function(x) x.CompareTo(NEWLINE)` – Jearca Dec 26 '14 at 04:10
Copy the entire function (not just the line with the `Array.FindIndex`) into http://converter.telerik.com and it will solve the conversion for you :) Its a good way to learn either C# or VB.Net when you only know one of the languages and wish to learn the other. – Jeremy Thompson Dec 26 '14 at 04:11
