擷取和更新實體

下列範例將使用 RetrieveEntityRequest 訊息擷取實體。 接著會藉由將 IsMailMergeEnabled 屬性設為 false 更新實體來停用合併列印，並且在 UpdateEntityRequest 將 HasNotes 設定為 true，指定實體應該包含與 Annotation 實體的關聯，如此實體才能顯示附註。

RetrieveEntityRequest retrieveBankAccountEntityRequest = new RetrieveEntityRequest
{
 EntityFilters = EntityFilters.Entity,
 LogicalName = _customEntityName
};
RetrieveEntityResponse retrieveBankAccountEntityResponse = (RetrieveEntityResponse)_serviceProxy.Execute(retrieveBankAccountEntityRequest);
EntityMetadata BankAccountEntity = retrieveBankAccountEntityResponse.EntityMetadata;

// Disable Mail merge
BankAccountEntity.IsMailMergeEnabled = new BooleanManagedProperty(false);
// Enable Notes
UpdateEntityRequest updateBankAccountRequest = new UpdateEntityRequest
{
 Entity = BankAccountEntity,
 HasNotes = true
};



_serviceProxy.Execute(updateBankAccountRequest);

Dim retrieveBankAccountEntityRequest As RetrieveEntityRequest = New RetrieveEntityRequest With {
 .EntityFilters = EntityFilters.Entity,
 .LogicalName = _customEntityName
}
Dim retrieveBankAccountEntityResponse As RetrieveEntityResponse = CType(_serviceProxy.Execute(retrieveBankAccountEntityRequest), RetrieveEntityResponse)
Dim BankAccountEntity As EntityMetadata = retrieveBankAccountEntityResponse.EntityMetadata

' Disable Mail merge
BankAccountEntity.IsMailMergeEnabled = New BooleanManagedProperty(False)
' Enable Notes
Dim updateBankAccountRequest As UpdateEntityRequest = New UpdateEntityRequest With {
 .Entity = BankAccountEntity,
 .HasNotes = True
}
_serviceProxy.Execute(updateBankAccountRequest)

刪除自訂實體

下列範例將使用 DeleteEntityRequest 訊息刪除採用 _customEntityName 變數所指定邏輯名稱的實體。

DeleteEntityRequest request = new DeleteEntityRequest()
{
 LogicalName = _customEntityName,
};
_serviceProxy.Execute(request);

Dim request As New DeleteEntityRequest() With {.LogicalName = _customEntityName}
_serviceProxy.Execute(request)
