MySql Server安装步骤如下所示:
1安装MySql Server
2 安装MySqlServer管理工具
解压中文语言包,将文件复制到安装目录下覆盖
文件覆盖后,打开软件设置语言为中文(CN)
3 MySqlServer开发注意事项(C#)
1.联接字符串:"Server=localhost;Database=100;Uid=root;Pwd='root'"
2.引用MySql.Data.dll;using MySql.Data.MySqlClient;
3.使用MySqlConnection、MySqlParameter、MySqlDataAdapter、MySqlCommandBuilder、MySqlCommand、MySqlDataAdapter、MySqlTransaction等类
5.使用MySqlCommand. ExecuteScalar()方法返回的object如果要转为int类型,必须使用Convert来强制转换,否则可能会出错。
6.修改记录时,字段数据类型如果为Bit类型的时候,Sql语句中的字段值要使用Ture或False,不能像SqlServer中一样使用0或1。
7.命令行工具:
public class Cmd { /// <summary> /// 执行Cmd命令 /// </summary> /// <param name="workingDirectory">要启动的进程的目录</param> /// <param name="command">要执行的命令</param> public static void StartCmd(String workingDirectory, String command) { Process p = new Process(); p.StartInfo.FileName = "cmd.exe"; p.StartInfo.WorkingDirectory = workingDirectory; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardInput = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.StartInfo.CreateNoWindow = true; p.Start(); p.StandardInput.WriteLine(command); Thread.Sleep(10000); //p.StandardInput.WriteLine("exit"); } public static void StartCmd() { Process p = new Process(); p.StartInfo.FileName = "cmd.exe"; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardInput = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.StartInfo.CreateNoWindow = true; p.Start(); p.StandardInput.WriteLine("net stop mysql"); Thread.Sleep(5000); p.StandardInput.WriteLine("net start mysql"); Thread.Sleep(5000); p.StandardInput.WriteLine("exit"); } }
备份:
public static bool BackUp(string backupPath) { try { //构建执行的命令 StringBuilder sbcommand = new StringBuilder(); sbcommand.AppendFormat("mysqldump -f -l -q -uroot -proot Sciendox50 -r \"{0}\"", backupPath); String command = sbcommand.ToString(); //获取mysqldump.exe所在路径 String appDirecroty = @"C:\Program Files\MySQL\MySQL Server 5.5\bin\"; Cmd.StartCmd(appDirecroty, command); Cmd.StartCmd();//重启mysql服务 MessageBox.Show(@"数据库已成功备份到 " + backupPath + " 文件中", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); return true; } catch (Exception) { MessageBox.Show("数据库备份失败!"); return false; } }
还原:
/// <summary> /// 数据还原 /// </summary> /// <param name="FilePath">文件路径</param> /// <returns></returns> public static bool RestoreDB(string FilePath) { try { StringBuilder sbcommand = new StringBuilder(); //在文件路径后面加上""避免空格出现异常 sbcommand.AppendFormat("mysql -uroot -proot Sciendox50 <\"{0}\"", FilePath); String command = sbcommand.ToString(); //获取mysql.exe所在路径 String appDirecroty = @"C:\Program Files\MySQL\MySQL Server 5.5\bin\"; DialogResult result = MessageBox.Show("您是否真的想覆盖以前的数据库吗?那么以前的数据库数据将丢失!!!", "警告", MessageBoxButtons.YesNo, MessageBoxIcon.Warning); if (result == DialogResult.Yes) { Cmd.StartCmd(appDirecroty, command); Cmd.StartCmd();//重启mysql服务 MessageBox.Show("数据库还原成功!"); return true; } return false; } catch (Exception) { MessageBox.Show("数据库还原失败!"); return false; } }
