C#实现数据库名称获取、数据库备份和还原

实现数据库的备份：
SqlConnection conn = new SqlConnection(connection);
string databaseName=@"E:\Data\Test.mdf"; //指定数据库名称(完整路径)
conn.Open();
string bakSQL = @"backup database @DataBaseName to disk=N'E:\Temp\Test.bak'";     //数据库备份SQL语句
try
{
SqlCommand cmd = new SqlCommand(bakSQL,conn);
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@DataBaseName",databaseName);  //参数
cmd.ExecuteNonQuery();
}
catch (Exception ee)
{
Console.WriteLine(ee);
}

数据库备份的还原：(待修改)

public static void Restore()
{

SqlConnection conn = new SqlConnection(connection);
try
{
conn.Open();

//杀掉数据库连接的进程
SqlCommand killCmd = new SqlCommand("use master; SELECT spid FROM sysprocesses ,sysdatabases WHERE sysprocesses.dbid=sysdatabases.dbid AND sysdatabases.Name='Test'", conn);
SqlDataReader myreader = killCmd.ExecuteReader();
ArrayList list = new ArrayList();
while (myreader.Read())
{
list.Add(myreader.GetInt16(0));

}
myreader.Close();
for (int i = 0; i < list.Count; i++)
{
killCmd = new SqlCommand(string.Format("KILL{0}",list[i]),conn);
killCmd.ExecuteNonQuery();
Console.WriteLine(string.Format("Kill线程{0}",i));
}

//数据库文件恢复
string restoreSQL = @"restore database test from disk=N'E:\Temp\Test.bak' with  move 'Test' to 'D:\\Data.mdf'";//此处为SQL恢复语句，报错，待修改
SqlCommand cmd = new SqlCommand(restoreSQL, conn);
cmd.CommandType = CommandType.Text;

cmd.ExecuteNonQuery();
}
catch(Exception ee)
{
Console.WriteLine(ee);
}

获取当前连接的SQL Server数据库名称：

public static void GetDataBaseName()
{

SqlConnection conn = new SqlConnection(connection);
try
{
conn.Open();
string bakSQL = "select db_name(); ";               //查询当前使用的数据库名字的SQL语句
SqlCommand cmd = new SqlCommand(bakSQL, conn);
cmd.CommandType = CommandType.Text;
SqlDataReader myreader = cmd.ExecuteReader();
if (myreader.Read())
{
Console.WriteLine(myreader.GetString(0));          //在控制台输出
}
else
{
Console.WriteLine("无结果");
}

}
catch(Exception ee)
{
Console.WriteLine(ee);
}
}

用SQL Server自带的存储过程，获取主机上所有数据库的名称，并将数据库名称的集合绑定到DropDownList控件上：

SqlConnection connection = new ConnString().GetSqlConn();
SqlCommand command = new SqlCommand("sp_helpdb", connection);
command.CommandType = CommandType.StoredProcedure;
connection.Open();
SqlDataReader reader = command.ExecuteReader();
ddlDatabaseList.DataSource = reader;
ddlDatabaseList.DataTextField = "Name";
ddlDatabaseList.DataBind();
reader.Close();
connection.Close();

在上述实现数据库的恢复时候出错，希望老鸟给予指点！
