FileInputStreamFileProgramUserFileInputStreamFileProgramUser指定文件路径创建File对象创建FileInputStream对象读取文件内容获取字节数组返回字节数组 上述序列图展示了用户指定文件路径后,程序的执行流程。程序首先根据文件路径创建一个File对象,然后创建一个FileInputStream对象来读取文件内容,并最终返回字节数组给用户。
using System; namespace CS01 { class Program { public static void swap(ref int x, ref int y) { int temp = x; x = y; y = temp; } public static void Main (string[] args) { int a = 5, b = 10; swap (ref a, ref b); // a = 10, b = 5; Console.WriteLine ("a = ...
While we’ve learned to read large files so far, sometimes we need to split them into smaller files or send them over the network in smaller sizes. First, we’ll begin by splitting the large file into smaller files, each with a specific size. ...
