SharePoint Web Service series: Add or update other types of items

We have discussed how to add or update a user-type item. This is because the user type is special. As the end of the SharePoint Web Service series, we will discuss how to write various other types of items.
The SDK contains the following table. Our writing relies entirely on this basis.
 

Name	Format
Attachments	System. Boolean
Boolean	System. Boolean
Calculated	N/
Choice	System. String
Computed	N/
Counter	System. int32
Crossprojectlink	System. Boolean
Currency	System. Double
Datetime	System. datetime
Gridchoice	System. String
Guid	System. guid
Integer	System. int32
Lookup	System. String
Maxitems	System. int32
Modstat	System. int32
Multichoice	System. String
Note	System. String
Number	System. Double
Recurrence	System. Boolean
Text	System. String
Threading	System. String
URL	System. String, system. String
User	System. String

This table shows the comparison between various field types in WSS and the corresponding data types in. net. Based on this, we can easily write the content in the <field> element.
For example, we want to add or update a URL-type field. You can write the field like this: <field name = "someurl"> http://www.example.com, example </field>

In this example, the someurl field of a list item is of the link type. We need to write a link to this field. The URL for this link is http://www.example.com and titled example ".
Note: For link fields, you can leave the title empty. (In this way, the system uses the address content as the title by default, which is the same as many text editors .) So the above example can also be written as follows: <field name = "someurl"> http://www.example.com, </field>

Another example is to add or update an option field. You can write the field as follows: <field name = "status"> completed </field>

The Status field in the task list is of the Option type. because it corresponds to system. String, you can directly write it like this.
