Hi all, I'm currently working on a college project using Visual studio 2008< C#,windows form application.

In the very 1st part of my program, i need to generate a large number of double array [144], like 10 thousand of them. It is very time-consuming and i need to repeat the step everytime i start my program.

So, i'm thinkin of generating these large number of double array and store it into some external data. Then everytime i start my program, my program will load these large number of double array in the program memory.

So, can i acchieve this by using I/O stream? How?

The simples way will be serialization. You can use binary or XML one.

I think that XML one will be OK for you. Check XmlSerializer on MSDN.

You could best use the BinaryWriter Read/Write overload functions for Double to do that.

http://msdn.microsoft.com/en-us/library/ez8wcba9.aspx[^]

For seeking you simply take the index and multiply it with the size of a double to get at the correct file position.

BinaryWriterObject.Seek(index * sizeof(double), SeekOrigin.Begin);

Good luck!
