C＃FileStream读取集编码 [英] C# FileStream read set encoding

问题描述

这里可能缺少一些明显的东西，但是我似乎无法在读取的FileStream上设置编码。代码如下：

There might be something obvious I'm missing here, but I can't seem to set the encoding on my FileStream read. Here's the code:

FileStream fs = new FileStream(file, FileMode.Open, FileAccess.Read);
            using (fs)
            {

                byte[] buffer = new byte[chunk];
                fs.Seek(chunk, SeekOrigin.Begin);
                int bytesRead = fs.Read(buffer, 0, chunk);
                while (bytesRead > 0)
                {
                    ProcessChunk(buffer, bytesRead, database, id);
                    bytesRead = fs.Read(buffer, 0, chunk);
                }

            }
            fs.Close();

ProcessChunk将读取的值保存到对象中，然后将这些对象序列化为XML，但是读取的字符出现错误。编码必须为1250。我还没有看到将编码添加到FileStream的选项。我在这里缺少什么？

Where ProcessChunk saves the read values to objects which are then serialized to XML, but the characters read appear wrong. The encoding needs to be 1250. I haven't seen an option to add the encoding to the FileStream. What am I missing here?

推荐答案

使用StreamReader而不是FileStream。它具有几个构造函数，可让您指定编码。例如：

Rather than FileStream, use StreamReader. It has several constructors which allow you to specify the Encoding. For example:

StreamReader sr = new StreamReader(file, System.Text.Encoding.ASCII);

由于您需要编码1250，因此可以通过以下方式完成：

Since you require encoding 1250, this can be done with:

StreamReader sr = new StreamReader(file, System.Text.Encoding.GetEncoding(1250));

我也建议将其写为：

using (StreamReader sr = new StreamReader ...etc)

而不是在using之外声明变量；而且您无需在使用之外执行关闭操作，因为则由Dispose处理。。

rather than declaring the variable outside the using; and you don't need to do the Close outside the using, since the Dispose will handle that.
