You'll need to look at the datasheet to find out the correct address of the sensor and the commands to send to the sensor in order to read from it. The first thing to do is get that data sheet. Do you have the datasheet?

As for the C# code, I cannot help you there as I don't know C, there may be an example in the SDK example files though, in which case just substitute the example I2C device info for that of the sensor you want to use.

yes, here it isPS-MPU-6000A-00v3.4.pdf

Here is an example of getting i2c response from the BlinkM...

  
  // Send the value 0x67 to the address of the blinkM
  // According to the datasheet, this will tell the BlinkM to put 3 bytes in the receive buffer
  // The 3 bytes represent the RGB (Red, Green and Blue) values
  _ezb.I2C.Write(0x09, new byte[] { 0x67 });

  // Read the 3 bytes in the receive buffer from the BlinkM
  byte [] ret = _ezb.I2C.Read(I2C.ReadArgsEnum.Auto, 0x09, 3);

I still am a bit confused! The imu that I have, I want to read the data that it gives and since it is 6dof, should it return 6 bytes? and I did this sort of a thing, let me know if I did it correct:

byte[] ret = ezB_Connect1.EZB.I2C.Read(EZ_B.I2C.ReadArgsEnum.Auto, 0x68, 6);

Also, I need to know which address to read from.

you would need to first tell the device that you wish to receive data before you can Read data.

Notice in my example that the first line requests data, and the second line reads the data.
