Binary data reading

Administrator

Hi! I am having problem reading binary ( in fact any file) file using the following code: Here is the code: FileStream fs=new FileStream("C:\abc.dat", System.IO.FileMode.Open, System.IO.FileAccess.Read); byte[] b=new byte[fs.Length - 1]; int fslen=(int) fs.Length; fs.Read(b,0,fslen); I am getting error: Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection. Same code works fine with vb: Dim f As System.IO.File Dim fs As System.IO.FileStream fs = f.Open("C:\abc.dat ", IO.FileMode.Open, IO.FileAccess.Read) Dim b(fs.Length - 1) As Byte fs.Read(b, 0, fs.Length) any idea? Thanks in Advance.

I think you should write this: byte[] b = new byte[fs.Length]; Because you have to write the total amount of bytes needed in the table if you declare a table. In vb Dim b(fs.Lengt-1) is the index of the endbyte in your tabel. It declares a tabel from index 0 to index 'fs.Lengt-1' So in c# you have to take care of the element at index zero. For example, if your file contains 200 bytes you have to declare a table with 200 cells. byte[] b = new byte[200]; in vb for the same file: (but 199 is the index from the endbyte in the table) Dim b(199) As Byte From 0 to 199 are also 200 bytes. You wrote byte[] b = new byte[199] and then, your are missing a cell for the latest byte. Then you get that error message.
