我有同样的问题，WebBrowser使用旧版本的IE浏览器，一些谷歌搜索我碰到以下代码，使更改到注册表，使WebBrowser使用最新的IE版本可能：
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 WBEmulato { 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; } } 您只需要创建一个类并将其放入该代码中，然后在程序启动时运行以下代码：
if (!WBEmulator.IsBrowserEmulationSet()) { WBEmulator.SetBrowserEmulationVersion(); }用set -e内建：
#!/bin/bashset -e# Any subsequent(*) commands which fail will cause the shell script to exit immediately或者，您可以传递-e命令行：
bash -e my_script.sh
您也可以使用禁用此行为set +e。
注意：
壳确实不退出如果失败的命令是紧跟在所述命令列表的一部分而或直到关键字，以下测试的一部分，如果或elif的保留字，在执行任何命令的一部分&&或|| 列表，除了最后的&&或||之后的命令 ，在管道中的任何命令，但最后，或者如果命令的返回值被反转 ！
