The SoapOperationBinding type exposes the following members.

Public methodSoapOperationBindingInitializes a new instance of the SoapOperationBinding class.

Public propertyHandledGets or sets a value indicating whether the ServiceDescriptionFormatExtension is used by the import process when the extensibility element is imported. (Inherited from ServiceDescriptionFormatExtension.)
Public propertyParentGets the parent of the ServiceDescriptionFormatExtension. (Inherited from ServiceDescriptionFormatExtension.)
Public propertyRequiredGets or sets a value indicating whether the ServiceDescriptionFormatExtension is necessary for the action to which it refers. (Inherited from ServiceDescriptionFormatExtension.)
Public propertySoapActionGets or sets the URI for the SOAP header.
Public propertyStyleGets or sets the type of SOAP binding used by the SoapOperationBinding.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

This class specifies that the message transmission will use SOAP and provides details about how the SOAP message will be formatted.
