c#訪問mysql資料庫的方法
(2)安裝mysql-connector-net
然後直接在windows作業系統安裝mysql-connector-net-6.3.8.msi
預設是安裝在c盤:
c:\program files\mysql\mysql connector net 6.3.8\assemblies
v2.0
v4.0
安裝完後我選擇的是v2.0版本的
然後在應用工程中引用元件mysql.data.dll
(3)封裝資料庫訪問元件dbconnectionmysql
/// /// mysql資料庫
/// 版本 mysql-connector-net-6.3.8.msi

public override dbparameter createparameter(string name)
public override dbparameter createparameter(string name, dbtype dbtype, object value)
public override dbparameter createparameter(string name, dbtype dbtype, int size, object value)
}
(4)客戶端訪問測試開發例項
[csharp] view plaincopy
public void testcshape_mysql()
//插入語句
x = "insert into xp_users(gid,uid,uname,***,email,pwd) values('";
x += "1','hsg77','何***',1,'[email protected]','1')";
if (dbw.executequery(x) > 0)
//查詢語句
datatable dt = dbw.executedatatable("select * from xp_users");
if (dt != null && dt.rows.count > 0)
if (dt != null)
dbw.dispose();
dbw = null;
}

Hybird APP (混合開發)簡介
第四類應用理論上講已經不太能歸類到hybrid開發的範疇了。這類應用使用了頁面動態化框架,可以讓native通過執行動態化的指令碼 可以本地也可以下發 但渲染出native的介面和邏輯。最出名的框架就是facebook的react native了,當然,每個大廠都會有自己造的輪子,比如阿里系的wee...
