[英]How to read and write .img files using FileStream in c#?
我正在尝试读取图像文件并将其写入新文件。 但写入的图像文件不是受支持的文件。 请告诉我读/写图像文件的正确方法是什么。 帮我!!
这是我的完整代码。 我没有收到任何错误。
using System;
using System.IO;
namespace readfile
{
class Program
{
static int totalbyte = 0;
static void Main(string[] args)
{
string path = "C:/Users/Nitesh Rathi/Downloads/"; // file's path.
string filename = "IMG_20200317_150302.jpg"; // file's name.
string fullpath = path + filename;
readfile(fullpath);
writefile(filename);
Console.ReadKey(false);
}
static void readfile(string path)
{
FileStream stm = File.Open(path, FileMode.Open); // open a file using filestream.
int size = (int)stm.Length; // size of the file.
byte[] data = new byte[stm.Length]; // file buffer.
while (size > 0) // loop until file' size is not 0.
{
int read = stm.ReadByte(); // reading file's data.
size -= read;
totalbyte += read;
}
}
static void writefile(string filename)
{
FileStream stm = File.Create(filename); // create a new file.
byte[] data = new byte[totalbyte]; // file's data.
Console.WriteLine("Writing data into file...");
stm.Write(data, 0, data.Length); // writing data into created file.
Console.WriteLine("data has been wrote into file.");
stm.Close();
}
}
}
我还使用了FileStream.Read()
方法。 但这对我也不起作用。
我找出了我的代码中的问题并修复了我的代码。
请参阅我的固定代码。 看看我做了什么改变。
Public static byte[] data; // this variable will be store file's content.
static void readfile(string path)
{
FileStream stm = File.Open(path, FileMode.Open); // open a file using filestream.
int size = (int)stm.Length; // size of the file.
data = new byte[size];
while (size > 0) // loop until file' size is not 0.
{
int read = stm.read(data, totalbyte, size); // reading file's data.
size -= read;
totalbyte += read;
}
}
static void writefile(string filename)
{
FileStream stm = File.Create(filename); // create a new file.
byte[] bytes = data;
Console.WriteLine("Writing data into file...");
stm.Write(data, 0, data.Length); // writing data into created file.
Console.WriteLine("data has been wrote into file.");
stm.Close();
}
