AccessDataSourceDesigner.DataFile 屬性

定義

實作設計工具屬性,以遮蔽關聯控制項的 DataFile 屬性。

public:
 property System::String ^ DataFile { System::String ^ get(); void set(System::String ^ value); };
public string DataFile { get; set; }
member this.DataFile : string with get, set
Public Property DataFile As String

屬性值

String,包含與 AccessDataSource 產生關聯的資料檔名稱和路徑。

範例

下列程式代碼範例示範如何使用 DataFile 屬性,在設計時間顯示與控件佔位元元中控件相關聯的 AccessDataSource Access 數據檔名稱和路徑。

此程式代碼範例是針對 類別提供的較大範例的 AccessDataSourceDesigner 一部分。

// Generate design time markup.
public override string GetDesignTimeHtml()
{
    // Generate a design-time placeholder containing the 
    // DataFile and the ConnectionString properties.
    // Split the ConnectionString into segments so it doesn't make
    // placeholder too wide.
    string[] connectParts = GetConnectionString().Split(new char[] { ';' });
    string connectString = "  " + connectParts[0];

    for (int i = 1; i < connectParts.Length; i++)
        connectString += ";<br>  " + connectParts[i].Trim();

    return CreatePlaceHolderDesignTimeHtml(
        "DataFile: " + DataFile + "<br />" +
        "Connection string:<br />" + connectString);
}
' Generate design time markup.
Public Overrides Function GetDesignTimeHtml() As String
    ' Generate a design-time placeholder containing the 
    ' DataFile and the ConnectionString properties.
    ' Split the ConnectionString into segments so it doesn't make
    ' placeholder too wide.
    Dim connectParts() As String
    connectParts = GetConnectionString().Split((";").ToCharArray())
    Dim connectString As String
    connectString = "  " & connectParts(0)

    Dim i As Integer
    For i = 1 To connectParts.Length - 1
        connectString &= ";<br>  " & connectParts(i).Trim()
    Next

    Return CreatePlaceHolderDesignTimeHtml( _
        "DataFile: " & DataFile & "<br />" & _
        "Connection string:<br />" & connectString)
End Function

備註

DataFile 設計工具中的 屬性設定為包含要用於相關聯 AccessDataSource 控件之 Microsoft Access 資料庫之.mdb檔案的名稱和路徑。
