041006 A DB 亂碼

    Q. string strSql = "INSERT INTO TBL_GYOMUTANGO ";
    strSql += "(WORD) ";
    strSql += "VALUES('" +strKey + "')";
    -->strKey 是漢字時，程序顯示爲亂碼。

    A. 使用Parameters解決亂碼
    string strSql = "INSERT INTO TBL_GYOMUTANGO ";
    strSql += "(WORD, COMMENT) ";
    strSql += "VALUES(@strKey,@strComment)";
              
    SqlCommand cmd = new SqlCommand(strSql,conn,trans);
    cmd.Parameters.Add(new SqlParameter("@strKey",SqlDbType.VarChar,50));
    cmd.Parameters.Add(new SqlParameter("@strComment",SqlDbType.NVarChar ,200));
    cmd.Parameters["@strKey"].Value = strKey;
    cmd.Parameters["@strComment"].Value = strComment;
    //SqlCommand cmd = new SqlCommand(strSql,conn);
    cmd.CommandType = CommandType.Text;
    iRet = cmd.ExecuteNonQuery();
