c# - 使用 Adomd 连接到分析服务时出错

Question

当我尝试连接到分析服务时，我遇到了异常。

我的代码

using AdomdConnection conn = new AdomdConnection("Data Source=.\\MSSQL2019;Catalog=OLAP1");
        try
        {
            conn.Open();
            string commandText = query;

            AdomdCommand cmd = new AdomdCommand(commandText, conn);
            AdomdDataReader dr = cmd.ExecuteReader();
            List<DimentionItemDto> dimentionItems = new List<DimentionItemDto>();
            while (dr.Read())
            {
                 //...
            }

            conn.Close();
            return dimentionItems;
        }
        catch (Exception ex)
        {
            logger.LogError(ex);
            return new List<DimentionItemDto>();
        }

The JSON object contains a trailing comma at the end which is not supported in this mode. Change the reader options. LineNumber: 23 | BytePositionInLine: 4.

例外

JSON 对象末尾包含一个逗号，此模式不支持该逗号。更改阅读器选项。行号：23 | 字节位置内线：4。

我猜这个异常来自你没有给出代码“//...”，是json字符串转换为列表实体异常
