Can A LINQ Or A LAMBDA Expression Be Used To Count The 1's In A Binary String Or Char Array
Sep 15, 2010Can a LINQ or a LAMBDA expression be used to count the 1's in a binary string ?For example, if I convert a number to its BINARY using.>>
Dim binaryString As String = Convert.ToString( numberVariable, 2 )
1) Without using a loop such as a FOR NEXT loop, can I count the number of 1's in the STRING using LINQ or a LAMBDA expression?
2) Can I get the indexes of where the 1's are at in a collection such as a LIST using LINQ or a LAMBDA expression?I know the syntax of some LINQ expressions, however, I don't know which method may be suitable.

VS 2008 : Converting A "binary String" Into A Byte Or Char?
May 23, 2010I've been trying to figure this out for hours now, and I've given up on trying to solve it myself. Basically what I need to do, is convert a "double octet" binary string, such as "11010011 01011101", into a byte or char type if possible.I use the following code to convert my Unicode text into binary:
Private Function ByteToStr(ByVal bt() As Byte) As String
Dim st As New StringBuilder
For Each byt As Byte In bt
[code]....
But that gives me weird results. The "Convert.FromBase64String" obviously isn't what I'm after. Any help would be great. If I can convert the "binary string" into a bytes or chars I can get it into a string.

View 4 RepliesStrip Any Non-numeric Value From A String?
Oct 24, 2007I know Val() is a VB6 function, but one thing I like about it is that you can wrap a string in it and it will "extract" the numerical value from the string if there are other things present (i.e. Val("123 Main St.") returns 123). This is the way my teacher taught us to use it. I know about the .TryParse and .Parse methods of the different data types, and how those can be used to check for a numerical value, but is there a replacement that can strip any non-numeric value from a string to put it in an integer (or double, single, decimal, etc.)?
