流读取器.读取字符数 [英] Stream reader.Read number of character

问题描述

是否有任何Stream读取器类从 string 中仅读取 char 或从 byte [] 中的 byte >?

Is there any Stream reader Class to read only number of char from string Or byte from byte[]?

例如读取字符串:

string chunk = streamReader.ReadChars(5); // Read next 5 chars

或读取字节

byte[] bytes = streamReader.ReadBytes(5); // Read next 5 bytes

请注意，此方法的返回类型或类的名称无关紧要.我只想知道是否有类似的东西，那么我可以使用它.

Note that the return type of this method or name of the class does not matter. I just want to know if there is some thing similar to this then i can use it.

我从midi File中获得了 byte [] .我想用C#读取此midi文件.但是我需要能够读取字节数.或字符(如果我将其转换为十六进制).要验证Midi并更轻松地从中读取数据.

I have byte[] from midi File. I want to Read this midi file in C#. But i need ability to read number of bytes. or chars(if i convert it to hex). To validate midi and read data from it more easily.

推荐答案

感谢您的评论.我不知道读取方法有重载.我可以使用FileStream实现这一点.

Thanks for the comments. I didnt know there is an Overload for Read Methods. i could achieve this with FileStream.

        using (FileStream fileStream = new FileStream(path, FileMode.Open))
        {
            byte[] chunk = new byte[4];
            fileStream.Read(chunk, 0, 4);
            string hexLetters = BitConverter.ToString(chunk); // 4 Hex Letters that i need!
        }
