Adding StaadPro.dll will not help in C# application. You need to add the interop dll. 
 Please create the dll by following steps: 
 1. Open up command prompt. 
 2. Go to C: or D: or any folder other than &lsquo;Program files&rsquo; or system folders 
 3. Now, type "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\x64\TlbImp.exe" " C:\Program Files\Bentley\Engineering\STAAD.Pro CONNECT Edition\STAAD\StaadPro.dll" /out:Interop.StaadPro.dll 
 The output DLL will be found in the folder where your command prompt is pointing. 
 Now, add this dll to your C# project and you can access the OpenStaad application object.

Hi Vivek, Chinna, 
 I am attaching a sample project which will demo how to connect to a running STAAD instance and query data. 
 Please note the following: 
 1. Launch an instance of STAAD and open a model file 
 2. Launch Visual Studio 2017 and open the attached Sample project. (Note: configuration should be a x64 one) 
 3. Build the project and run it. 
 4. It will print the node numbers in the opened model. The sample project uses the geometry interface. Likewise you can use others. 
 SampleOSApp.zip 
 
 Note: If you want to access specific instance of STAAD, please refer /cfs-file/__key/communityserver-discussions-components-files/5932/Using-OpenSTAAD-application-object.pdf . This refers to an old version of deployment but the code snippets provided is still valid. 
 Hope this helps all.
