如何直接使用.Net读取磁盘？

string filePath = "path/to/your/file.txt";
string content = File.ReadAllText(filePath);

string filePath = "path/to/your/file.txt";
using (StreamReader reader = new StreamReader(filePath))
{
    string content = reader.ReadToEnd();
}

string filePath = "path/to/your/file.bin";
using (BinaryReader reader = new BinaryReader(File.Open(filePath, FileMode.Open)))
{
    byte[] content = reader.ReadBytes((int)reader.BaseStream.Length);
}
