Start D435i with C#

Hi,

I want to start a new C# solution of  realsense.

My steps are as follow:

1. Creat a new C# solution. I add "Intel.Realsense.dll"(x64) to reference.

2. I can't add "realsense2.dll" to reference.So I copy "realsense2.dll" (from Intel RealSense SDK 2.0\bin\x64) to the Debug file of my solution.

3. I execute the code:

var pipe = new Pipeline();
pipe.Start();

while (true)
{
    using (var frames = pipe.WaitForFrames())
    using (var depth = frames.DepthFrame)
    {
        Console.WriteLine("The camera is pointing at an object " +
            depth.GetDistance(depth.Width / 2, depth.Height / 2) + " meters away\t");

        Console.SetCursorPosition(0, 0);
    }
}

the error occurs at line:

using (var frames = pipe.WaitForFrames())

it shows "System.Exception: 'Frame didn't arrive within 5000'

ExternalException: rs2_pipeline_wait_for_frames(pipe:0000000021A2BA30) "

my platform is WIN10 , Visual Studio 2017 , SDK version 2.32.1

I tried the C# wrappers and Intel RealSense Viewer,and they worked perfectly, so I think my camera and cable are fine.

And I want to know what steps I missed or did it wrong?

THX!
