    Apply License

    To apply evaluation/production license in GcExcel .NET, the long string key needs to be copied to the code in one of the following two ways.


    • To license all the workbooks in a project

      C#
      Copy Code
      Workbook.SetLicenseKey(" Your License Key");
    • To license an instance of the workbook

      C#
      Copy Code
      var workbook = new Workbook("Your License Key");


    • To license all the workbooks in a project, add the license key in Startup.cs file by using SetLicenseKey method. This will license all the workbooks even across multiple Controllers. 

      Startup.cs
      Copy Code
      public Startup(IConfiguration configuration)
              {
                  //Apply license before using the API, otherwise it will be considered as no license.
                  Workbook.SetLicenseKey(" Your License Key");
                      
              }
    • To license an instance of the workbook, add the license key when an instance of workbook is created. Add the following code in the Index() method of the controller:

      GcExcelController.cs
      Copy Code
      public IActionResult Index()
              {
                  //Apply license before using the API, otherwise it will be considered as no license.
                  var workbook = new Workbook("Your License Key");
                      
              }
