问题:

I have a mysql database with utf8_general_ci encoding ,

i'm connecting to the same database with php using utf-8 page and file encode and no problem but when connection mysql with C# i have letters like this غزة

i editit the connection string to be like this

server=localhost;password=root;User Id=root;Persist Security Info=True;database=mydatabase;Character Set=utf8

but the same problem .

回答1:

Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword; CharSet=utf8;

Note! Use lower case value utf8 and not upper case UTF8 as this will fail.

See http://www.connectionstrings.com/mysql



回答2:

could you try:

Server=localhost;Port=3306;Database=xxx;Uid=x xx;Pwd=xxxx;charset=utf8;"

Edit: I got a new idea:

//To encode a string to UTF8 encoding
string source = "hello world";
byte [] UTF8encodes = UTF8Encoding.UTF8.GetBytes(source);

//get the string from UTF8 encoding
string plainText = UTF8Encoding.UTF8.GetString(UTF8encodes);

good luck
