There are several overloads available for users to be able to set up the license and key files.
Below are a few ways to do this:

The first way is by using two strings: RasterSupport.SetLicense(string, string)
There are several ways to set a string variable in C# and VB so we have included a couple of different examples depending on your personal preference.
C#

Code:


using Leadtools;
using Leadtools.Codecs;

namespace SetLicense_console_cs
{
	class Program
	{
		static void Main(string[] args)
		{
			//SetLicense(string, string) Method
			string licenseFilePath = @"C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC"; //Your .LIC file path here
			string developerKey = System.IO.File.ReadAllText(@"C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC.key"); //Your .KEY file path here

			RasterSupport.SetLicense(licenseFilePath, developerKey);

			//Tests to see if license supports a particular type
			bool isLocked = RasterSupport.IsLocked(RasterSupportType.Document);

			if (isLocked)
				Console.WriteLine("Document support is locked");
			else
				Console.WriteLine("Document support is unlocked");

			Console.ReadKey();
		}
	}
}

Code:


Imports Leadtools
Imports Leadtools.Codecs

Module Module1

    Sub Main()

        'SetLicense(string, string) Method
        Dim licenseFilePath As String = "C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC" 'Your .LIC file path here
        Dim developerKey As String = System.IO.File.ReadAllText("C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC.key") 'Your .KEY file path here
        RasterSupport.SetLicense(licenseFilePath, developerKey)

        Dim isLocked As Boolean = RasterSupport.IsLocked(RasterSupportType.Document)

        If (isLocked) Then
            Console.WriteLine("Document support is locked")
        Else
            Console.WriteLine("Document support is unlocked")
        End If

        Console.ReadLine()

    End Sub

End Module

Code:


using Leadtools;
using Leadtools.Codecs;

namespace SetLicense_console_cs
{
	class Program
	{
		static void Main(string[] args)
		{
			//SetLicense(string, string) Method
			string licenseFilePath = @"C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC"; //Your .LIC file path here
			string developerKey = ""; //Copy your key contents to this string location

			RasterSupport.SetLicense(licenseFilePath, developerKey);

			//Tests to see if license supports a particular type
			bool isLocked = RasterSupport.IsLocked(RasterSupportType.Document);

			if (isLocked)
				Console.WriteLine("Document support is locked");
			else
				Console.WriteLine("Document support is unlocked");

			Console.ReadKey();
		}
	}
}

Code:


Imports Leadtools
Imports Leadtools.Codecs

Module Module1

    Sub Main()

        'SetLicense(string, string) Method
        Dim licenseFilePath As String = "C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC" 'Your .LIC file path
        Dim developerKey As String = "" 'Copy your key contents to this string location
        RasterSupport.SetLicense(licenseFilePath, developerKey)

        Dim isLocked As Boolean = RasterSupport.IsLocked(RasterSupportType.Document)

        If (isLocked) Then
            Console.WriteLine("Document support is locked")
        Else
            Console.WriteLine("Document support is unlocked")
        End If

        Console.ReadLine()

    End Sub

End Module

The Next way is by using a stream and a string: RasterSupport.SetLicense(Stream, string)

C#

Code:


using Leadtools;
using Leadtools.Codecs;

namespace SetLicense_console_cs
{
	class Program
	{
		static void Main(string[] args)
		{
			//SetLicense(Stream, string) Method
			Stream licenseStream = File.OpenRead(@"C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC");
			string developerKey = ""; //Copy your key contents to this string location

			RasterSupport.SetLicense(licenseStream, developerKey);

			//Tests to see if license supports a particular type
			bool isLocked = RasterSupport.IsLocked(RasterSupportType.Document);

			if (isLocked)
				Console.WriteLine("Document support is locked");
			else
				Console.WriteLine("Document support is unlocked");

			Console.ReadKey();
		}
	}
}

Code:


Imports Leadtools
Imports Leadtools.Codecs

Module Module1

    Sub Main()

        'SetLicense(Stream, string) Method
        Dim licenseStream As FileStream = File.OpenRead("C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC")
        Dim developerKey As String = "" 'Copy your key contents to this string location

        RasterSupport.SetLicense(licenseStream, developerKey)

        Dim isLocked As Boolean = RasterSupport.IsLocked(RasterSupportType.Document)

        If (isLocked) Then
            Console.WriteLine("Document support is locked")
        Else
            Console.WriteLine("Document support is unlocked")
        End If

        Console.ReadLine()

    End Sub

End Module

The Last way is by using bytes and a string: RasterSupport.SetLicense(Byte[], string)

C#

Code:


using Leadtools;
using Leadtools.Codecs;

namespace SetLicense_console_cs
{
	class Program
	{
		static void Main(string[] args)
		{
			//SetLicense(Byte[], String) Method
			byte[] licenseBuffer = System.IO.File.ReadAllBytes(@"C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC"); //Your .LIC file path here
			string developerKey = ""; //Copy your key contents to this string location

			RasterSupport.SetLicense(licenseBuffer, developerKey);

			//Tests to see if license supports a particular type
			bool isLocked = RasterSupport.IsLocked(RasterSupportType.Document);

			if (isLocked)
				Console.WriteLine("Document support is locked");
			else
				Console.WriteLine("Document support is unlocked");

			Console.ReadKey();
		}
	}
}

Code:


Imports Leadtools
Imports Leadtools.Codecs

Module Module1

    Sub Main()

        'SetLicense(Byte[], String) Method
        Dim licenseBuffer = System.IO.File.ReadAllBytes("C:\LEADTOOLS21\Support\Common\License\LEADTOOLS.LIC") 'Your .LIC file path here
        Dim developerKey As String = "" 'Copy your key contents to this string location

        RasterSupport.SetLicense(licenseBuffer, developerKey)

        Dim isLocked As Boolean = RasterSupport.IsLocked(RasterSupportType.Document)

        If (isLocked) Then
            Console.WriteLine("Document support is locked")
        Else
            Console.WriteLine("Document support is unlocked")
        End If

        Console.ReadLine()

    End Sub

End Module
