Public API and Backward Incompatible Changes
New public enumeration WiFiEncryptionType was added to specify various encryption types for the WiFi QR Code entities
This enumeration keeps supported WiFi encryption types.
New public enumeration
/// <summary>
/// Represents WiFi Encryption type.
/// </summary>
[Obfuscation(Feature = "internalization", Exclude = true, ApplyToMembers = true)]
[Flags]
public enum WiFiEncryptionType
{
/// <summary>Represents no encryption WiFi type.</summary>
None = 0,
/// <summary>Represents WiFi with the WPA encryption type.</summary>
WPA = 1,
/// <summary>Represents WiFi with the WPA-EAP encryption type.</summary>
WPAEAP = 2,
/// <summary>Represents WiFi with the WPA/WPA2 encryption type.</summary>
WPAWPA2 = 3,
/// <summary>Represents WiFi with the WEP encryption type.</summary>
WEP = 4,
}
Public class WiFi was added to provide WiFi QR Code object properties
Class [WiFi] contains following properties to get or set.
The following example demonstrates how to create WiFi QR Code standard entry.
Create QR Code signature with WiFi
public static void Run()
{
using (Signature signature = new Signature(filePath))
{
// create WiFi object
WiFi wifi = new WiFi()
{
SSID = "GuestNetwork!",
Encryption = WiFiEncryptionType.WPAWPA2,
Password = "guest",
Hidden = false
};
// create options
QrCodeSignOptions options = new QrCodeSignOptions
{
EncodeType = QrCodeTypes.QR,
// setup Data property to SMS instance
Data = wifi,
// set right bottom corner
HorizontalAlignment = HorizontalAlignment.Left,
VerticalAlignment = VerticalAlignment.Center,
Width = 100,
Height = 100,
Margin = new Padding(10)
};
// sign document to file
signature.Sign(outputFilePath, options);
Console.WriteLine($"\nSource document signed successfully with {signResult.Succeeded.Count} signature(s).\nFile saved at {outputFilePath}.");
}
}
