Saya memiliki masalah yang sama, WebBrowser menggunakan versi lama IE, dengan beberapa googling saya menemukan kode berikut yang membuat perubahan ke dalam registri dan membuat WebBrowser untuk menggunakan versi IE terbaru yang mungkin:
public enum BrowserEmulationVersion
{
Default = 0,
Version7 = 7000,
Version8 = 8000,
Version8Standards = 8888,
Version9 = 9000,
Version9Standards = 9999,
Version10 = 10000,
Version10Standards = 10001,
Version11 = 11000,
Version11Edge = 11001
}
public static class WBEmulator
{
private const string InternetExplorerRootKey = @"Software\Microsoft\Internet Explorer";
public static int GetInternetExplorerMajorVersion()
{
int result;
result = 0;
try
{
RegistryKey key;
key = Registry.LocalMachine.OpenSubKey(InternetExplorerRootKey);
if (key != null)
{
object value;
value = key.GetValue("svcVersion", null) ?? key.GetValue("Version", null);
if (value != null)
{
string version;
int separator;
version = value.ToString();
separator = version.IndexOf('.');
if (separator != -1)
{
int.TryParse(version.Substring(0, separator), out result);
}
}
}
}
catch (SecurityException)
{
// The user does not have the permissions required to read from the registry key.
}
catch (UnauthorizedAccessException)
{
// The user does not have the necessary registry rights.
}
return result;
}
private const string BrowserEmulationKey = InternetExplorerRootKey + @"\Main\FeatureControl\FEATURE_BROWSER_EMULATION";
public static BrowserEmulationVersion GetBrowserEmulationVersion()
{
BrowserEmulationVersion result;
result = BrowserEmulationVersion.Default;
try
{
RegistryKey key;
key = Registry.CurrentUser.OpenSubKey(BrowserEmulationKey, true);
if (key != null)
{
string programName;
object value;
programName = Path.GetFileName(Environment.GetCommandLineArgs()[0]);
value = key.GetValue(programName, null);
if (value != null)
{
result = (BrowserEmulationVersion)Convert.ToInt32(value);
}
}
}
catch (SecurityException)
{
// The user does not have the permissions required to read from the registry key.
}
catch (UnauthorizedAccessException)
{
// The user does not have the necessary registry rights.
}
return result;
}
public static bool SetBrowserEmulationVersion(BrowserEmulationVersion browserEmulationVersion)
{
bool result;
result = false;
try
{
RegistryKey key;
key = Registry.CurrentUser.OpenSubKey(BrowserEmulationKey, true);
if (key != null)
{
string programName;
programName = Path.GetFileName(Environment.GetCommandLineArgs()[0]);
if (browserEmulationVersion != BrowserEmulationVersion.Default)
{
// if it's a valid value, update or create the value
key.SetValue(programName, (int)browserEmulationVersion, RegistryValueKind.DWord);
}
else
{
// otherwise, remove the existing value
key.DeleteValue(programName, false);
}
result = true;
}
}
catch (SecurityException)
{
// The user does not have the permissions required to read from the registry key.
}
catch (UnauthorizedAccessException)
{
// The user does not have the necessary registry rights.
}
return result;
}
public static bool SetBrowserEmulationVersion()
{
int ieVersion;
BrowserEmulationVersion emulationCode;
ieVersion = GetInternetExplorerMajorVersion();
if (ieVersion >= 11)
{
emulationCode = BrowserEmulationVersion.Version11;
}
else
{
switch (ieVersion)
{
case 10:
emulationCode = BrowserEmulationVersion.Version10;
break;
case 9:
emulationCode = BrowserEmulationVersion.Version9;
break;
case 8:
emulationCode = BrowserEmulationVersion.Version8;
break;
default:
emulationCode = BrowserEmulationVersion.Version7;
break;
}
}
return SetBrowserEmulationVersion(emulationCode);
}
public static bool IsBrowserEmulationSet()
{
return GetBrowserEmulationVersion() != BrowserEmulationVersion.Default;
}
}
Anda hanya perlu membuat kelas dan memasukkan kode ini di dalamnya, lalu jalankan kode berikut saat program dimulai:
if (!WBEmulator.IsBrowserEmulationSet())
{
WBEmulator.SetBrowserEmulationVersion();
}
VB.NET:
Imports Microsoft.Win32
Imports System
Imports System.Collections.Generic
Imports System.IO
Imports System.Linq
Imports System.Security
Imports System.Text
Imports System.Threading.Tasks
Public Enum BrowserEmulationVersion
[Default] = 0
Version7 = 7000
Version8 = 8000
Version8Standards = 8888
Version9 = 9000
Version9Standards = 9999
Version10 = 10000
Version10Standards = 10001
Version11 = 11000
Version11Edge = 11001
End Enum
Public Class WBEmulator
Private Const InternetExplorerRootKey As String = "Software\Microsoft\Internet Explorer"
Public Shared Function GetInternetExplorerMajorVersion() As Integer

Try
Dim key As RegistryKey

End Try

key.DeleteValue(programName, False)

End If
Catch ex As SecurityException

End Try
SetBrowserEmulationVersion = result
End Function
Public Shared Function SetBrowserEmulationVersion() As Boolean
Dim ieVersion As Integer
Dim emulationCode As BrowserEmulationVersion
ieVersion = GetInternetExplorerMajorVersion()
If ieVersion >= 11 Then

Select Case ieVersion

Anda dapat menggunakannya seperti:
If Not WBEmulator.IsBrowserEmulationSet() Then
WBEmulator.SetBrowserEmulationVersion()
End If
