https://blog.csdn.net/xpj8888/article/details/84999413 C# 基础(十二)C# 文本文件的读写、清零,将文本文件的内容读到字符串:主要应用在写日志
很显然,上述的几篇博客,大概讲述了Filestream的读写、BinaryReader的读写。其实,在C#中,我们常常可以用BinaryReader/Writer类、StreamReader/Writer类、filestream类、File类读写文件及其区别。
byte[] bytPictureContent = new byte[0]; //图片内容 byte[] bytPictureContent2 = new byte[0]; //图片内容 /// <summary> /// 图片转字节 /// </summary> /// <param name="Path"></param> /// <returns></returns> private byte[] ImageConvertToByte(string Path) { byte[] bytContent = new byte[0]; try { FileStream fs = new FileStream(Path, FileMode.Open, FileAccess.Read); bytContent = new byte[fs.Length]; fs.Read(bytContent, 0, Convert.ToInt32(fs.Length)); fs.Close(); } catch(Exception ex) { MessageBox.Show("SendPackageFunc()——图片转字节发生错误" + ex.ToString()); } return bytContent; } private byte[] ImageConvertToByte2(string Path) { byte[] bytContent = new byte[0]; try { using (BinaryReader reader = new BinaryReader(File.Open(Path, FileMode.Open))) { //reader.Read(bytContent, 0, bytContent.Length); bytContent = reader.ReadBytes(bytPictureContent.Length); } } catch (Exception ex) { MessageBox.Show("SendPackageFunc()——图片转字节发生错误" + ex.ToString()); } return bytContent; }
