使用C#動(dòng)態(tài)創(chuàng)建Access數(shù)據(jù)庫及密碼

    以前工作中需要全新的Access數(shù)據(jù)庫，可以復(fù)制數(shù)據(jù)庫，也可以把新的數(shù)據(jù)庫放到資源里面，用新數(shù)據(jù)庫的時(shí)候釋放出來，都感覺不爽，還是動(dòng)態(tài)生成心理舒服。生成數(shù)據(jù)庫要使用ADO，首先添加引用。
    using System.IO;
    using System.Data.OleDb; //連接Access數(shù)據(jù)庫
    using ADOX;
    //引用COM：Microsoft ADO Ext. 2.8 for DDL and Security
    //添加引用：Microsoft ActioveX Data Objects 2.8 Library
    創(chuàng)建數(shù)據(jù)庫：然后使用ADODB創(chuàng)建數(shù)據(jù)庫，直接看代碼：
    string conn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName;
    //創(chuàng)建數(shù)據(jù)庫
    ADOX.Catalog catalog = new Catalog();
    try
    {
    catalog.Create(conn);
    }
    catch
    {}
    //連接數(shù)據(jù)庫
    ADODB.Connection cn = new ADODB.Connection();
    cn.Open(conn, null, null, -1);
    catalog.ActiveConnection = cn;
    //新建表
    ADOX.Table table = new ADOX.Table();
    table.Name = "AdPlayList";
    ADOX.Column column = new ADOX.Column();
    column.ParentCatalog = catalog;
    column.Type = ADOX.DataTypeEnum.adInteger; // 必須先設(shè)置字段類型
    column.Name = "ID";
    column.DefinedSize = 9;
    column.Properties["AutoIncrement"].Value = true;
    table.Columns.Append(column, DataTypeEnum.adInteger, 0);
    //設(shè)置主鍵
    table.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "ID", "", "");
    table.Columns.Append("FileName", DataTypeEnum.adVarWChar, 50);
    table.Columns.Append("FileDate", DataTypeEnum.adDate, 0);
    table.Columns.Append("FileSize", DataTypeEnum.adInteger, 9);
    table.Columns.Append("OrderID", DataTypeEnum.adInteger, 9);
    table.Columns.Append("Sha1", DataTypeEnum.adVarWChar, 50);
    try
    {
    catalog.Tables.Append(table);
    }
    catch (Exception ex)
    {
    MessageBox.Show(ex.Message);
    }
    //此處一定要關(guān)閉連接，否則添加數(shù)據(jù)時(shí)候會出錯(cuò)
    table = null;
    catalog = null;
    Application.DoEvents();
