在谷歌搜索后,使用下面的代码仍然无法编译

decimal h = Convert.ToDecimal("2.09550901805872E-05");   
decimal h2 = Decimal.Parse("2.09550901805872E-05", System.Globalization.NumberStyles.AllowExponent);

我正在使用Acrobat Reader 11.0.3和Windows 7,Visual Studio 2012,并且已经在Manage Addon中启用了Acrobat Reader

并按照WPF webbrowser在Adobe阅读器窗口中打开PDF文件

尝试两种方法后仍然有错误

即使使用管理员帐户打开WPF程序,也会取消对网页的导航

private void CheckAndFixWebBrowserRenderingEngine()
        {
            RegistryKey baseRegistryKey = Registry.LocalMachine;
            string renderingEngineSubKeyString = @"SOFTWARE";

            // 64bit operationg systems have another registry path
            if (Environment.Is64BitOperatingSystem)
            {
                renderingEngineSubKeyString += @"\Wow6432Node";
            }

            renderingEngineSubKeyString += @"\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION";

            //var assemblyValueKey = System.IO.Path.GetFileName(App.ResourceAssembly.Location);
            var assemblyValueKey = System.IO.Path.GetFileName(System.Windows.Application.ResourceAssembly.Location);

            var renderingEngingeValue = 9999; // check other values below

            try
            {
                RegistryKey sk1 = baseRegistryKey.CreateSubKey(renderingEngineSubKeyString);

                var value = sk1.GetValue(assemblyValueKey);
                if (value == null || value.ToString() != renderingEngingeValue.ToString())
                { …

有两个主键a和b一个键可以编译两个键怎么样

var product = db.TMP_HELLO.FirstOrDefault<TMP_HELLO>(instrmnt => (instrmnt.a == good.a; instrmnt.b == good.b));
