.config dex log 之前 fig 添加 code for 設定
用WebClient 去下載數據時發現有服務器提交了協議沖突. Section=ResponseHeader Detail=CR 後面必須是 LF錯誤，解決辦法
1.在app.config種添加 web 在 web.config種添加
<system.net>
<settings>
<httpWebRequest useUnsafeHeaderParsing="true" />
</settings>
</system.net>
2.以反射的形式在程序中設定useUnsafeHeaderParsing的值【該方法須在發送請求之前進行設定否則無效果】public static bool SetAllowUnsafeHeaderParsing(bool useUnsafe) { //Get the assembly that contains the internal class System.Reflection.Assembly aNetAssembly = System.Reflection.Assembly.GetAssembly(typeof(System.Net.Configuration.SettingsSection)); if (aNetAssembly != null) { //Use the assembly in order to get the internal type for the internal class Type aSettingsType = aNetAssembly.GetType("System.Net.Configuration.SettingsSectionInternal"); if (aSettingsType != null) { //Use the internal static property to get an instance of the internal settings class.//If the static instance isn‘t created allready the property will create it for us. object anInstance = aSettingsType.InvokeMember("Section", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.NonPublic, null, null, new object[] { }); if (anInstance != null) { //Locate the private bool field that tells the framework is unsafe header parsing should be allowed or not System.Reflection.FieldInfo aUseUnsafeHeaderParsing = aSettingsType.GetField("useUnsafeHeaderParsing", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance); if (aUseUnsafeHeaderParsing != null) { aUseUnsafeHeaderParsing.SetValue(anInstance, useUnsafe); return true; } } } } return false; }
