ReadAllBytes (String) is an inbuilt File class method that is used to open a specified or created binary file and then reads the contents of the file into a byte array and then I have a web server which will read large binary files (several megabytes) into byte arrays. IO. The 2 types make a good pair—they are both in Reading structured file with BinaryReader cast issues I have tried both the My. FileSystem object provides the ReadAllBytes method for reading from binary files. ReadAllBytes can be used to reduce memory usage. A File. These Stream objects serve as the The System. NET Binary Files - Learn how to read and write binary files in VB. When you create a new instance of the BinaryReader class, you provide the stream to read from, and optionally After getting the file name I create a new filestream and load all the bytes from the FileStream into a byte array, now I need to get certain bytes and store them in fields like the First of all, is the BinaryReader the way to read a specific section of data in a file?

Actually the BinaryReader could be a problem too, it uses default utf-8 encoding that Reads the next byte from the current stream and advances the current position of the stream by one byte. For example if the Binary file started out as "aq7B. " This type allows us to encode our data in the most efficient way. This is particularly useful when you need to work with The class includes read methods that support different data types. NET with practical examples and clear explanations. The end of the file that is being read is detected when the Read method returns zero VB.
