DataContractResolver.ResolveName Method

Override this method to map the specified xsi:type name and namespace to a data contract type during deserialization.

Namespace:  System.Runtime.Serialization
Assembly:  System.Runtime.Serialization (in System.Runtime.Serialization.dll)

public abstract Type ResolveName(
	string typeName,
	string typeNamespace,
	Type declaredType,
	DataContractResolver knownTypeResolver


Type: System.String
The xsi:type name to map.
Type: System.String
The xsi:type namespace to map.
Type: System.Type
The type declared in the data contract.
Type: System.Runtime.Serialization.DataContractResolver
The known type resolver.

Return Value

Type: System.Type
The type the xsi:type name and namespace is mapped to.

If you want to use the known type resolution logic inside your implementation, a reference to it is passed in as the knownTypeResolver parameter.

The following example shows an implementation of the ResolveName(String, String, Type, DataContractResolver) method.

// Used at deserialization
// Allows users to map xsi:type name to any Type 
public override Type ResolveName(string typeName, string typeNamespace, Type declaredType, DataContractResolver knownTypeResolver)
    XmlDictionaryString tName;
    XmlDictionaryString tNamespace;
    if (dictionary.TryGetValue(typeName, out tName) && dictionary.TryGetValue(typeNamespace, out tNamespace))
        return this.assembly.GetType(tNamespace.Value + "." + tName.Value);
        return null;
