Assuming you're interested in Eikon .NET APIs, you can find tutorials which give a thorough walk through all the functionality available through this API following the link below.

If you would like to use the newer Eikon Data APIs in C#, you may want to check out this open source project:

Thanks for the help. I am also looking at the C# API using Interop.EikonDesktopDataAPI.dll, Interop.RSearch.dll, etc., which is simply introduced here https://developers.thomsonreuters.com/eikon-com/eikon-desktop-data-api/docs?content=786&type=documentation_item. I don't see the github open source project using those functions. Do you have any other sources providing manual for using APIs like Interop.RSearch.dll?

Yes. Click on the Tutorials tab on the introductory page you referenced.

I have followed the sample code to lunch "new EikonDesktopDataAPI.EikonDesktopDataAPI();", but got the following error:

Additional information: Retrieving the COM class factory for component with CLSID {70B3E69B-E207-412E-8A27-E94A01F96728} failed due to the following error: 8007007e The specified module could not be found. (Exception from HRESULT: 0x8007007E)..

It looks like some COM component is required. Do you have any solution for this?

Are you running the sample on the machine where Eikon is installed? Search Windows registry for {70B3E69B-E207-412E-8A27-E94A01F96728}. If Eikon is installed on the machine, you should find this COM class UUID in the registry. On a 64-bit Windows box you should have the following registry key: HKCR\Wow6432Node\CLSID\{70B3E69B-E207-412E-8A27-E94A01F96728}

Make sure you compile the application as 32-bit. Eikon COM libraries are all 32-bit and can only be used in 32-bit processes.
