Among our many APIs, FileCatalyst offers a way to integrate into a .NET platform using the FileCatalyst .NET DLL. The DLL can be used in C# applications as well as VB and C++.
The DLL is a wrapper around our command line interface (CLI) tool. We wrote code to generate command line arguments as well as parse the output of the transfers. Since the CLI takes care of all transfers, there is no additional overhead to the transfer if you use the DLL.
To get started with the DLL, contact a sales person for download access.
Once the zip archive is obtained, extract it and place the FileCatalystAPI.dll file in the bin folder of your application. Users will also need to copy the FileCatalystCL.jar file to the same location as the DLL. The archive also includes a help file. The help file gives access to all the exposed Properties as well as other Classes users may wish to use.
Below is a sample file to help users get started with uploading a file using .NET with acceleration. Simply replace the values in
