c# - 在 C# 中,在 DLL 中捕获 SOAP

我正在构建一个 DLL,它应该被我正在构建的其他一些应用程序使用。DLL 的部分功能是记录所有 SOAP 事务。

我找到了关于如何在 C# 中捕获 SOAP 事务的解释。 https://web.archive.org/web/20160402053148/http://blog.encoresystems.net/articles/how-to-capture-soap-envelopes-when-consuming-a-web-service.aspx

我的问题是它需要将以下内容添加到 app.config(链接页面末尾)。

<system.web>
<webServices>
<soapExtensionTypes>
<add type="Encore.PayPal.Soap.TraceExtension, Encore.PayPal.Soap" priority="1" group="0" />
</soapExtensionTypes>
</webServices>
</system.web>

我不希望所有使用我的 DLL 的人都需要将其添加到 app.config。

有没有办法在加载 DLL 时即时执行此操作?

最佳答案

我在 MSDN 论坛上发现了一个类似的问题:Programmatically registering a SOAP Extension

/// <summary>  
/// Programatically registers a <see cref="SoapExtension"/> at runtime with the specified
/// <see cref="SoapExtensionTypeElement.Priority"/> and <see cref="SoapExtensionTypeElement.Group"/> settings.
/// </summary>
/// <param name="type">The <see cref="Type"/> of the <see cref="SoapExtension"/> to register.</param>
/// <param name="priority">
/// A value that indicates the relative order in which this SOAP extension runs when multiple SOAP extensions are
/// specified. Within each group the priority attribute distinguishes the overall relative priority of the SOAP
/// extension. A lower priority number indicates a higher priority for the SOAP extension. The lowest possible
/// value for the priority attribute is 1.
/// </param>
/// <param name="group">
/// The relative priority group (e.g. Low or High) in which this SOAP extension runs when multiple SOAP extensions
/// are configured to run.
/// </param>
[ReflectionPermission(SecurityAction.Demand, Unrestricted = true)]
public static void RegisterSoapExtension(Type type, int priority, PriorityGroup group)
{
if (!type.IsSubclassOf(typeof(SoapExtension)))
{
throw new ArgumentException("Type must be derived from SoapException.", "type");
}

if (priority < 1)
{
throw new ArgumentOutOfRangeException("priority", priority, "Priority must be greater or equal to 1.");
}

// get the current web services settings...
WebServicesSection wss = WebServicesSection.Current;

// set SoapExtensionTypes collection to read/write...
FieldInfo readOnlyField = typeof(System.Configuration.ConfigurationElementCollection).GetField("bReadOnly", BindingFlags.NonPublic | BindingFlags.Instance);
readOnlyField.SetValue(wss.SoapExtensionTypes, false);

// inject SoapExtension...
wss.SoapExtensionTypes.Add(new SoapExtensionTypeElement(type, priority, group));

// set SoapExtensionTypes collection back to readonly and clear modified flags...
MethodInfo resetModifiedMethod = typeof(System.Configuration.ConfigurationElement).GetMethod("ResetModified", BindingFlags.NonPublic | BindingFlags.Instance);
resetModifiedMethod.Invoke(wss.SoapExtensionTypes, null);
MethodInfo setReadOnlyMethod = typeof(System.Configuration.ConfigurationElement).GetMethod("SetReadOnly", BindingFlags.NonPublic | BindingFlags.Instance);
setReadOnlyMethod.Invoke(wss.SoapExtensionTypes, null);
}

您需要在实例化客户端/服务器之前调用此方法。

RegisterSoapExtension(typeof(TraceExtension), 1, PriorityGroup.Low);
PaypalClient cli = new PaypalClient();
