    String^ messageText, 
    int dataCode, 
    array<unsigned char>^ dataBytes
)

member Log : 
        messageText:string * 
        dataCode:int * 
        dataBytes:byte[] -> unit

參數

• messageText
  型別：System. . :: . .String
  The text of the logging entry.

• dataCode
  型別：System. . :: . .Int32
  A field available for numeric data to be logged.

• dataBytes
  型別：array<System. . :: . .Byte> [] () [] []
  A field available for binary data to be logged.

備註

The Script component developer does not use the ScriptComponent class directly, but indirectly, by coding the methods and properties of the ScriptMain class, which inherits from ScriptComponent through the UserComponent class.

The developer can use the Log method of the ScriptMain class to log user-defined data to enabled log providers.

範例

The following code sample demonstrates how the Script component developer might log information from the component by using the Log method. For more information, see 在指令碼元件中記錄.

Dim bt(0) As Byte
Me.Log("Test Log Event", _
  0, _
  bt)
