在网上搜索了找到了小白的Blog上转了一个大富翁论坛上的讨论,看了讨论后发现里面提供的方法还不能直接用于ASP.NET。我对代码进行了稍稍的改动
void restoreButton_Click(object sender, System.EventArgs e) { string path = pathTextBox.Text; string dbname = dbDropDownList.SelectedValue;
string restoreSql = "use master;"; restoreSql = "restore database @dbname from disk = @path;"; string pai = "use master;ALTER DATABASE Wy SET OFFLINE WITH ROLLBACK IMMEDIATE;ALTER DATABASE Wy SET ONLINE WITH ROLLBACK IMMEDIATE"; SqlConnection conn = new SqlConnection(ConnStr); SqlCommand com1 = new SqlCommand(pai, conn);
SqlCommand myCommand = new SqlCommand(restoreSql, new SqlConnection(ConnStr));
myCommand.Parameters.Add("@dbname", SqlDbType.Char); myCommand.Parameters["@dbname"].Value = dbname; myCommand.Parameters.Add("@path", SqlDbType.Char); myCommand.Parameters["@path"].Value = path;
try { conn.Open(); com1.ExecuteNonQuery(); conn.Close(); myCommand.Connection.Open(); myCommand.ExecuteNonQuery(); infoLabel.Text = "恢复成功!<br>已经把备份" path "恢复到数据库";
} catch(Exception ex) { infoLabel.Text = "恢复失败!<br>出错信息如下:<br>" ex.ToString(); } finally { myCommand.Connection.Close();
} }
