C# BinaryReader.ReadString()方法如何从一个二进制文件中读出八个字符的字符串？

FileStream file = new FileStream("你要读的文件", FileMode.Open, FileAccess.Read);
BinaryReader read = new BinaryReader(file);
int count = (int)file.Length;
byte[] buffer = new byte[count];
read.Read(buffer, 0, buffer.Length);
string msg = Encoding.Default.GetString(buffer);
这样应该是可以了

using (BinaryReader br = new BinaryReader(new FileStream(@"c:\myfile.dat", FileMode.Open)))
{
string str;
while (br.PeekChar() != -1)
{
str = br.ReadString();
Console.WriteLine(str);
}
}
