Determining if the License is loaded successfully

Aspose.Cells provides Workbook.IsLicensed property which you can use to determine if the license is loaded successfully or not. If you access this property before setting the license, it will return false and if you will call this property after setting the license, it will return true indicating that license has been loaded successfully.

C# code to determine if the License is loaded successfully

The following code accesses the Workbook.IsLicensed property before setting a license and it returns false. Then it loads the license and accesses the property again which now returns true.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the License File
string licPath = @"Aspose.Cells.lic";

// Create workbook object before setting a license
Workbook workbook = new Workbook();

// Check if the license is loaded or not. It will return false
Console.WriteLine(workbook.IsLicensed);

try
{
    Aspose.Cells.License lic = new Aspose.Cells.License();
    lic.SetLicense(licPath);
}
catch (Exception ex)
{
    Console.WriteLine(ex.Message);
}

// Check if the license is loaded or not. Now it will return true
Console.WriteLine(workbook.IsLicensed);
