C# window Form程序
private void button1_Click(object sender, EventArgs e)
        {
            string connectionstring = "server=*******;database=charges;user id=sa;pwd=****";
            //建立连接
            SqlConnection conn = new SqlConnection(connectionstring);
            conn.Open();
            string path = @"F:\Test\数据库备份\datarestor\restor.bak";
            //备份语句
            string backupstr = "backup database charges to disk = '" + path + "'";
            SqlCommand cmd = new SqlCommand(backupstr, conn);
            try
            {
                conn.Open();
                cmd.ExecuteNonQuery();
                MessageBox.Show("备份成功！", "提示");

            }
            catch
            {
                MessageBox.Show("备份失败！", "提示");
            }
            finally
            {
                conn.Close();
            }

        }
结果总是提示“备份失败！”
在 SQL Server的查询分析器中 输入 backup database charges to disk = 'F:\\Test\\数据库备份\\datarestor\\restor.bak';执行，出息设备无法打开F:\\Test\\数据库备份\\datarestor\\restor.bak 访问遭到拒绝的错误。
问题不知道出在了哪里……请各位给看看……

明白了,谢谢
