Asking for help, clarification, or responding to other answers. The basic parameters that the read and write functions of binary files accept are: the memory address of the value to be written or read the number of bytes to read per block the total. Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information.Lossless compression is possible because most real-world data exhibits statistical redundancy. The stored objects have a tendency to break over time as the assumptions you make about the hardware no longer hold true (in this case that the sizeof (int) is constant and the endianess of int will not change). I am porting an application from C++ to C#, and am having trouble finding a way to quickly and efficiently write structures to a binary file. In the example are using two reads.

Complexity set to false. Close the stream. The output of the array changes if we change np .int8 to int32 or int64. Also tried messing with the file pointer, moving it back and forth and also leaving it as is to see if that has been the problem. fwrite and fread make task easier when you want to write and read blocks of data. Then look at binary Blobs only after you have shown that serialization has too much overhead (unlikely for most situations, but it is a possibility). In this case the filestream is declared within the Using, and it is disposed when it goes out of scope, so you don't have to worry about executing the Close method. If so, how? Generally speaking, the steps involved in reading and writing binary files are the same as for text files: Connect a stream to the file. Subsection 11.5.2 Reading Binary Data.
