public int Read(byte[] buffer, int offset, int count):
buffer-存放数据的数组;
offset-从buffer的那一位开始存放数据,offset需满足 0 < offset < buffer.Lenght-1;
count-读入buffer中数据的长度,count需要满足 0 < count < buffer.Lenght-offset;
eg:
System.IO.StreamReader sr =
new System.IO.StreamReader("d:\\pathtest.txt");
System.IO.Stream st = sr.BaseStream;
byte[] bts = new byte[1025];
int count =
st.Read(bts, 3, bts.Length-3);
int pos =(int)st.Position;
st.Position = 5;
while (count > 0)
{
count = st.Read(bts, 3, bts.Length-3);
}
byte[] bts = new byte[1025];
st.Read(bts, 0, bts.Length);
byte[] bts = new byte[1025];
st.Read(bts, 3, bts.Length-3);//从字节数组bts2的第3+1开始放数据
byte[] bts = new byte[1025];
st.Position = 5;//设置指针为当前流的第5位置
st.Read(bts, 3, bts.Length-3); //从当前流的第6位置开s始读取,并从字节数组bts2的第3+1开始放数据
