C# 使用C将xml加载到mysql#

我使用“加载本地xml”脚本将xml文件加载到带有C#的mysql数据库。 代码如下所示：

public void loadXML(string path, string table, string identify)
    {
        string query = "LOAD XML LOCAL INFILE ";
        query += "'"+path+"'";
        query += " INTO TABLE " + table;
        query += " Rows Identified By '<" + identify + ">';";
        System.Diagnostics.Debug.Print(query);
        if (this.OpenConnection() == true)
        {
            MySqlCommand cmd = new MySqlCommand(query, connection);

            //Execute command
            cmd.ExecuteNonQuery();

            //close connection
            this.CloseConnection();
        }

    } 

public void loadXML（字符串路径、字符串表、字符串标识）
{
string query=“加载XML本地填充”；
查询+=“'”+路径+“'”；
查询+=“入表”+表；
查询+=“由“”标识的行；”；
系统.诊断.调试.打印（查询）；
if（this.OpenConnection（）==true）
{
MySqlCommand cmd=新的MySqlCommand（查询、连接）；
//执行命令
cmd.ExecuteNonQuery（）；
//密切联系
这个.CloseConnection（）；
}
} 

然而，我无法得到这项工作。我与VS 2015合作。 它给出了一个mysqlException： “尝试读取结果集时遇到致命错误。” InnerException是找不到该文件，这很奇怪，因为该文件肯定不是我的目标文件

此处显示调试输出：
