CustomFieldDefinition Constructor (UInt32, Type)
Initializes a new instance of the CustomFieldDefinition class that contains a field ID and a field type.
Assembly: Microsoft.Synchronization.SimpleProviders (in Microsoft.Synchronization.SimpleProviders.dll)
Parameters
- fieldId
- Type: System::UInt32
An integer ID for the field.
- fieldType
- Type: System::Type
The data type of the field. For a list of supported types, see CustomFieldDefinition.
| Exception | Condition |
|---|---|
| SimpleProviderInvalidOperationException | fieldType was set to either byte[] or string, which is only supported by the three-parameter constructor. |
The following code examples provide input for the ItemMetadataSchema object. The constants in the sample code define an integer value for each column in the item store. These values are used when creating the custom field definitions and identity rules for the ItemMetadataSchema object. To view this code in the context of a complete application, see the "Sync101 using Simple Sync Provider" application that is available in the Sync Framework SDK and from Code Gallery.
