我需要从应用程序中清空一些表内容我使用那个 MySQL 命令系统，但它没有清空表的命令

        #region Delete
        public MySqlCommand Delete(string table, string column, string value)
        {
            _command = _command.Replace("<R>", "`" + table + "`");
            _command = _command.Replace("<C>", "`" + column + "`");
            _command = _command.Replace("<V>", "'" + value + "'");
            return this;
        }
        public MySqlCommand Delete(string table, string column, long value)
        {
            _command = _command.Replace("<R>", "`" + table + "`");
            _command = _command.Replace("<C>", "`" + column + "`");
            _command = _command.Replace("<V>", value.ToString());
            return this;
        }
        public MySqlCommand Delete(string table, string column, ulong value)
        {
            _command = _command.Replace("<R>", "`" + table + "`");
            _command = _command.Replace("<C>", "`" + column + "`");
            _command = _command.Replace("<V>", value.ToString());
            return this;
        }
        public MySqlCommand Delete(string table, string column, bool value)
        {
            _command = _command.Replace("<R>", "`" + table + "`");
            _command = _command.Replace("<C>", "`" + column + "`");
            _command = _command.Replace("<V>", (value ? "1" : "0"));
            return this;
        }

        #endregion

有人想清空桌子吗，谢谢

如果您设置为要处理的每个 mySQL 命令使用该类，则必须添加另一种类型，ClearAll或类似的：

_command = new StringBuilder("DELETE FROM <R>");

然后您必须将代码添加到其中一个Execute方法中（当然）
