How to use random reads? Would you please give me some example?

int org.apache.hadoop.dfs.DFSClient.DFSInputStream.read(long position, byte[] buffer, int offset, int length) throws IOException
This is random read.
Examples see in
org.apache.hadoop.dfs.TestPread

Which functions in hadoop support random reads?
And If I want to program with C#, how do I use the APIs?

Don't know about C#, sorry.
