EventLog.LogNameFromSourceName(String, String) 方法

定義

命名空間:

System.Diagnostics

組件:

System.Diagnostics.EventLog.dll

套件:

System.Diagnostics.EventLog v8.0.0

來源:

EventLog.cs

取得登錄指定來源的記錄檔的名稱。

public:
 static System::String ^ LogNameFromSourceName(System::String ^ source, System::String ^ machineName);

public static string LogNameFromSourceName (string source, string machineName);

static member LogNameFromSourceName : string * string -> string

Public Shared Function LogNameFromSourceName (source As String, machineName As String) As String

參數

source

String

事件來源的名稱。

machineName

String

要在其上搜尋記錄檔的電腦的名稱，或者表示本機電腦的 "."。

傳回

String

與登錄中指定的來源關聯的記錄檔名稱。

範例

下列範例會從本機計算機刪除來源。 此範例會從其來源判斷記錄檔，然後刪除記錄檔。

注意

多個來源可能會寫入事件記錄檔。 刪除自訂記錄檔之前，請確定沒有其他來源寫入該記錄檔。

備註

事件來源會指出記錄事件的內容。 如果應用程式很大，通常是應用程式的名稱，或應用程式的子元件名稱。 應用程式和服務應該寫入應用程式記錄檔或自定義記錄檔。 設備驅動器應該寫入系統記錄檔。

當您建立新的來源時，一次只能寫入一個記錄檔時，系統會使用事件記錄檔向事件記錄檔註冊您的應用程式，作為專案的有效來源。 屬性 Source 可以是任何字串，但計算機上其他來源無法使用名稱。 嘗試建立重複 Source 的值會擲回例外狀況。 不過，單一事件記錄檔可以寫入許多不同的來源。
