//Insert remark
[System.Web.Services.WebMethod]
public static void insert_remark(string remark)
{

string str_insert ="INSERT INTO remark VALUES(@remark)";

SqlParameter[] parameter = {
new SqlParameter("@remark", remark),
};
int abc = DBclass.TruyVan_XuLy_VoiThamSo(str_insert, parameter);
}

如果我的话："文本框中输入需要插入到数据库I CAN"作品的好代码。但当我输入："I CAN’T插入到数据库"，我得到这个错误：
