CustomFieldDefinition 建構 (UInt32, Type)

初始化 CustomFieldDefinition 類別的新執行個體，這個執行個體包含欄位識別碼和欄位類型。

命名空間: Microsoft.Synchronization.SimpleProviders
組件: Microsoft.Synchronization.SimpleProviders (在 microsoft.synchronization.simpleproviders.dll)

語法

'宣告
Public Sub New ( _
    fieldId As UInteger, _
    fieldType As Type _
)
'用途
Dim fieldId As UInteger
Dim fieldType As Type

Dim instance As New CustomFieldDefinition(fieldId, fieldType)

public CustomFieldDefinition (
    uint fieldId,
    Type fieldType
)

public:
CustomFieldDefinition (
    unsigned int fieldId, 
    Type^ fieldType
)

public CustomFieldDefinition (
    UInt32 fieldId, 
    Type fieldType
)

public function CustomFieldDefinition (
    fieldId : uint, 
    fieldType : Type
)

參數

• fieldId
  欄位的整數識別碼。

• fieldType
  欄位的資料類型。如需支援類型的清單，請參閱 CustomFieldDefinition。

範例

下列程式碼範例提供 ItemMetadataSchema 物件的輸入。範例程式碼中的常數定義項目存放區中每一資料行的整數值。這些值是在建立自訂欄位定義和 ItemMetadataSchema 物件的識別規則時使用。若要在完整應用程式的內容中檢視這段程式碼，請參閱 Sync Framework SDK 及 Code Gallery 中的 "Sync101 using Simple Sync Provider" 應用程式。

public const uint CUSTOM_FIELD_ID = 1;
public const uint CUSTOM_FIELD_TIMESTAMP = 2;

public override ItemMetadataSchema MetadataSchema
{
    get
    {
        CustomFieldDefinition[] customFields = new CustomFieldDefinition[2];
        customFields[0] = new CustomFieldDefinition(CUSTOM_FIELD_ID, typeof(ulong));
        customFields[1] = new CustomFieldDefinition(CUSTOM_FIELD_TIMESTAMP, typeof(ulong));

        IdentityRule[] identityRule = new IdentityRule[1];
        identityRule[0] = new IdentityRule(new uint[] { CUSTOM_FIELD_ID });

        return new ItemMetadataSchema(customFields, identityRule);
    }
}

Public Const CUSTOM_FIELD_ID As UInteger = 1
Public Const CUSTOM_FIELD_TIMESTAMP As UInteger = 2
Public Overrides ReadOnly Property MetadataSchema() As ItemMetadataSchema
    Get
        Dim customFields As CustomFieldDefinition() = New CustomFieldDefinition(1) {}
        customFields(0) = New CustomFieldDefinition(CUSTOM_FIELD_ID, GetType(ULong))
        customFields(1) = New CustomFieldDefinition(CUSTOM_FIELD_TIMESTAMP, GetType(ULong))

        Dim identityRule As IdentityRule() = New IdentityRule(0) {}
        identityRule(0) = New IdentityRule(New UInteger() {CUSTOM_FIELD_ID})

        Return New ItemMetadataSchema(customFields, identityRule)
    End Get
End Property
