Returns a license for the instance of the component, if one is available.

Namespace:   System.ComponentModel
Assembly:  System (in System.dll)

public override License GetLicense(
	LicenseContext context,
	Type type,
	object instance,
	bool allowExceptions
)

Parameters

context
Type: System.ComponentModel.LicenseContext

A LicenseContext that specifies where you can use the licensed object.

type
Type: System.Type

A Type that represents the component requesting the License.

instance
Type: System.Object

An object that requests the License.

allowExceptions
Type: System.Boolean

true if a LicenseException should be thrown when a component cannot be granted a license; otherwise, false.

Return Value

Type: System.ComponentModel.License

A valid License. If this method cannot find a valid License or a valid context parameter, it returns null.

At design time, the GetLicense method looks for a license file named myClassName.LIC, where myClassName is the FullName of the component to create. This file must be in the same directory as the .dll file that contains the component.

Next, this method checks the first line of the license file against a key specified in the IsKeyValid method. If the key is valid, this line is used as the LicenseKey.
