. NET Object serialization-TimeSpan

In WebServices, TimeSpan cannot be used as a system TimeSpan parameter. A new TimeSpan class is generated on the client.

I. Problem Reproduction

 

Create a Web Method with TimeSpan as the parameter:

1: [WebMethod]
2: public string HelloWorld (TimeSpan span)
3 :{
4: return "Hello World ";
5 :}
6:
View the WSDL file and see the following content:

1: <s: element name = "HelloWorld">
2:-<s: complexType>
3:-<s: sequence>
4: <s: element minOccurs = "1" maxOccurs = "1" name = "span" type = "tns: TimeSpan"/>
5: </s: sequence>
6: </s: complexType>
7: </s: element>
8: <s: complexType name = "TimeSpan"/>

When the client references Web Services, a new TimeSpan class is generated:

1: public partial class TimeSpan: object, System. Runtime. Serialization. IExtensibleDataObject, System. ComponentModel. INotifyPropertyChanged {
2:
3: [System. NonSerializedAttribute ()]
4: private System. Runtime. Serialization. ExtensionDataObject extensionDataField;
5:
6: [global: System. ComponentModel. BrowsableAttribute (false)]
7: public System. Runtime. Serialization. ExtensionDataObject ExtensionData {
8: get {
9: return this. extensionDataField;
10 :}
11: set {
12: this. extensionDataField = value;
13 :}
14 :}
15:
16: public event System. ComponentModel. PropertyChangedEventHandler PropertyChanged;
17:
18: protected void RaisePropertyChanged (string propertyName ){
19: System. ComponentModel. PropertyChangedEventHandler propertyChanged = this. PropertyChanged;
20: if (propertyChanged! = Null )){
21: propertyChanged (this, new System. ComponentModel. PropertyChangedEventArgs (propertyName ));
22 :}
23 :}
24 :}

 

 

The method can only use the TimeSpan generated above:

Ii. Solution

Extended TimeSpan:

1: public class TimeSpanEx
2 :{
3: [XmlElement (ElementName = "TimeSpan")]
4: public string TimeSpanAsString
5 :{
6: get {return TimeSpan! = Null? TimeSpan. ToString (): null ;}
7: set
8 :{
9: TimeSpan span;
10: if (value! = Null & TimeSpan. TryParse (value, out span ))
11: TimeSpan = span;
12: else
13: TimeSpan = new TimeSpan ();
14 :}
15 :}
16: [XmlIgnore]
17: public TimeSpan {get; set ;}
18 :}

Pass TimeSpan through TimeSpan:

1: [WebMethod]
2: public string HelloWorld (TimeSpanEx span)
3 :{
4: return "Hello World ";
5 :}
6:
Client example:

1: WebService1SoapClient client = new WebService1SoapClient ();
2: TimeSpanEx span = new TimeSpanEx ();
3: span. TimeSpan = new TimeSpan (1, 2, 3). ToString ();
4: client. HelloWorld (span );
5:
The TimeSpan result obtained by the server:
