C# 连接MySql的方法

1.从http://prdownloads.sourceforge.net/mysqldrivercs/MySQLDriverCS-n-EasyQueryTools-3.0.18.exe?download上下载MySQLDriverCS.
2.把MySQLDriverCS.dll.添加到.net的组件
3.使用方法
下面是创建一个数据库链接:
下面是创建一个数据库链接:
using MySQLDriverCS;

MySQLConnection conn = new MySQLConnection( new MySQLConnectionString("localhost","test","root","").AsString );
conn.Open();

如果你使用的是.net的集成开发环境(visual studio.net)那么在代码中输入MySQLDriverCS后再输入一个”.”就可以看到MySQLDriverCS名称空间中的所有的东西了.
下面是commond:
MySQLCommand cmd;
cmd = new MySQLDriverCS.MySQLCommand("DROP TABLE IF EXISTS test.mysqldrivercs_test",conn);
cmd.ExecuteNonQuery();
cmd.Dispose();

cmd = new MySQLDriverCS.MySQLCommand("CREATE TABLE test.mysqldrivercs_test("+
"SettingID tinyint(3) unsigned NOT NULL auto_increment,"+
"SettingValue text, "+
"PRIMARY KEY (SettingID), UNIQUE KEY SettingID(SettingID), KEY SettingID_2 (SettingID))"+
" TYPE=MyISAM COMMENT='MySQL test table'",conn);

cmd.ExecuteNonQuery();
cmd.Dispose();
下面是insert:
方法原型：
public MySQLInsertCommand(
MySQLConnection conn,
object[,] FieldsAndValues,
string Table
);
string Value = "Value";
int SettingID = 1;

new MySQLInsertCommand(conn,
new object[,] {{"field1",SettingID},{"field2",Value}},
"mysqldrivercs_test"
);
mysqldrivercs_test 是表名

下面是update
方法原型：
public MySQLUpdateCommand(
MySQLConnection conn,
object[,] FieldsAndValues,
string Table,
object[,] WhereParamFields,
string[,] WhereNoparamFields
);

Value = "Value2";
new MySQLUpdateCommand(conn,
new object[,] {{"SettingValue",Value}},
"mysqldrivercs_test",
new object[,] {{"SettingID","=",SettingID}},
null
);
下面是select
DataTable dt = new MySQLSelectCommand(conn,
new string[] {"SettingID","SettingValue"},
new string[] {"mysqldrivercs_test"},
new object[,] {{"SettingID","=",SettingID}},
null,
null
).Table;
string storedValue = dt.Rows[0]["SettingValue"].ToString();

下面是delete
new MySQLDeleteCommand(conn,"mysqldrivercs_test",new object[,] {{"SettingID","=",SettingID}},null);
关闭链接:
conn.Close();
