问题
I have the following property:
protected BasicHttpBinding Binding
{
get
{
var config = ConfigurationManager.GetSection("basicHttpBinding") as ServiceModelSectionGroup;
foreach (ChannelEndpointElement bindings in config.Bindings.BasicHttpBinding.Bindings)
{
string binding = bindings.Binding;
if (binding != null)
{
return new BasicHttpBinding(binding);
}
}
return null;
}
}
When I debug it, it fails with a null exception: Object reference not set to an instance of an object at this line:
foreach (ChannelEndpointElement bindings in config.Bindings.BasicHttpBinding.Bindings)
however, I notice that the line above it is also null.
here is the app.config file
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="IntelexWSSoap" closeTimeout="00:01:00" openTimeout="00:01:00"
receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="Transport">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
.....
</basicHttpBinding>
</bindings>
....
</system.serviceModel>
</configuration>
I can't figure out why it's failing.
回答1:
Try this:
var config = ConfigurationManager.GetSection("system.serviceModel/bindings") as
System.ServiceModel.Configuration.BindingsSection;
<basicHttpBinding>
isn't a configuration section, it's an element within the <bindings>
configuration section.
回答2:
Looks like you're getting the "basicHttpBinding" section but then trying to cast it as ServiceModelSectionGroup
which refers to the "system.serviceModel" section so it returns null
.
Try ConfigurationManager.GetSection("system.serviceModel")
instead.
