| 29 | +## Step 1: Check License File Existence |
| 30 | +```csharp |
| 31 | +if (File.Exists(Constants.LicensePath)) |
17 | 32 | { |
18 | | - /// <summary> |
19 | | - /// This example demonstrates how to set license from stream. |
20 | | - /// </summary> |
21 | | - class SetLicenseFromStream |
22 | | - { |
23 | | - public static void Run() |
24 | | - { |
25 | | - if (File.Exists(Constants.LicensePath)) |
26 | | - { |
27 | | - using (FileStream stream = File.OpenRead(Constants.LicensePath)) |
28 | | - { |
29 | | - License license = new License(); |
30 | | - license.SetLicense(stream); |
31 | | - } |
32 | | - |
33 | | - Console.WriteLine("License set successfully."); |
34 | | - } |
35 | | - else |
36 | | - { |
37 | | - Console.WriteLine("\nWe do not ship any license with this example. " + |
38 | | - "\nVisit the GroupDocs site to obtain either a temporary or permanent license. " + |
39 | | - "\nLearn more about licensing at https://purchase.groupdocs.com/faqs/licensing. " + |
40 | | - "\nLear how to request temporary license at https://purchase.groupdocs.com/temporary-license."); |
41 | | - } |
42 | | - } |
43 | | - } |
| 33 | +``` |
| 34 | +This step checks if the license file exists in the specified path. |
| 35 | +## Step 2: Set License from Stream |
| 36 | +```csharp |
| 37 | +using (FileStream stream = File.OpenRead(Constants.LicensePath)) |
| 38 | +{ |
| 39 | + License license = new License(); |
| 40 | + license.SetLicense(stream); |
44 | 41 | } |
45 | 42 | ``` |
| 43 | +If the license file exists, this step creates a file stream to read the license file and sets the license for GroupDocs.Comparison using the `SetLicense` method. |
| 44 | +## Step 3: Handle License Absence |
| 45 | +```csharp |
| 46 | +Console.WriteLine("License set successfully."); |
| 47 | +``` |
| 48 | +If the license is set successfully, this step prints a success message. |
| 49 | +## Step 4: Prompt for Obtaining License |
| 50 | +```csharp |
| 51 | +Console.WriteLine("\nWe do not ship any license with this example. " + |
| 52 | + "\nVisit the GroupDocs site to obtain either a temporary or permanent license. " + |
| 53 | + "\nLearn more about licensing at https://purchase.groupdocs.com/faqs/licensing. " + |
| 54 | + "\nLear how to request temporary license at https://purchase.groupdocs.com/temporary-license."); |
| 55 | +``` |
| 56 | +If the license file doesn't exist, this step prompts the user to obtain a license from the GroupDocs website. |
| 57 | + |
