[英]Stream reader.Read number of character
Is there any Stream reader Class to read only number of char
from string
Or byte
from byte[]
? 是否有任何流读取器类,以只读的数
char
从string
或者byte
从byte[]
forexample reading string: 例如读取字符串:
string chunk = streamReader.ReadChars(5); // Read next 5 chars
or reading bytes 或读取字节
byte[] bytes = streamReader.ReadBytes(5); // Read next 5 bytes
Note that the return type of this method or name of the class does not matter. 请注意,此方法的返回类型或类的名称无关紧要。 I just want to know if there is some thing similar to this then i can use it.
我只想知道是否有类似的东西,然后我可以使用它。
I have byte[]
from midi File. 我有midi File的
byte[]
。 I want to Read this midi file in C#. 我想用C#读取此midi文件。 But i need ability to read number of bytes.
但是我需要能够读取字节数。 or chars(if i convert it to hex).
或字符(如果我将其转换为十六进制)。 To validate midi and read data from it more easily.
验证Midi并更轻松地从中读取数据。
Thanks for the comments. 感谢您的评论。 I didnt know there is an Overload for Read Methods.
我不知道读取方法有重载。 i could achieve this with FileStream.
我可以用FileStream实现。
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!
}
You can achieve this by doing something like below but I am not sure this will applicable for your problem or not. 您可以通过执行以下操作来实现此目的,但是我不确定这是否适用于您的问题。
StreamReader sr = new StreamReader(stream);
StringBuilder S = new StringBuilder();
while(true)
{
S = S.Append(sr.ReadLine());
if (sr.EndOfStream == true)
{
break;
}
}
Once you have value on "S", you can consider sub strings from it. 一旦对“ S”具有值,就可以考虑其中的子字符串。
