MySQL ASP.NET 中文亂碼

 

原來除了MySQL本身資料編碼設定外

在ASP.NET中ODBC版本也有絕對的影響:

MySQL ODBC 3.51 Driver 只能顯示big5繁體中文
MySQL ODBC 5.1 Driver 能同時顯示utf8簡體繁體中文

web.config中連結字串差別:

dotNetFramework1.1:

<add key="MySQLConnStr" value="DRIVER={MySQL ODBC 3.51 Driver};Database=[strDatabaseName];Server=[strServerName];UID=[strUserName];PWD=[strPassword];OPTION=3;CharSet=big5;"/>

dotNetFramework2.0以上:

<add name="MySQLConnStr" connectionString="DRIVER={MySQL ODBC 5.1 Driver};Database=[strDatabaseName];Server=[strServerName];UID=[strUserName];PWD=[strPassword];OPTION=3;"/>
