Question

我在应用程序中实现了一个方法，当它从visual studio运行时很好，但是当它从任务调度程序运行时在日志文件中出现此错误

System.Exception：同步过程中发生异常，同时获取供应商列表和方法名称为GetSuppliers。异常是Newtonsoft.Json.JsonReaderException：解析值时遇到意外的字符：C。第0行，位于Newtonsoft.Json.JsonTextReader.ParseValue（）的Newtonsoft.Json.JsonTextReader.ParseValue（），位于Newtonsoft.Json.Json.JsonTextReader的Newtonsoft.Json.JsonTextReader.ReadInternal（）。在Newtonsoft.Json.Serialization

的Newtonsoft.Json.Serialization.JsonSerializerInternalReader.ReadForType（JsonReader reader，JsonContract contract，Boolean hasConverter，Boolean inArray）中的.Read（）

我的方法

 public string GetSuppliers()
{
    SqlConnection connect = null; var spdb = new Syncdbsource();
    try
    {
        var hsp = new hspservice.MyServiceSoapClient("MyServiceSoap");

        var sdetails = hsp.GetSupplier();
        List<SupplierDetails> supplierslist = null; var countSuppliers = 0;

        if (!string.IsNullOrEmpty(sdetails))
        { supplierslist = JsonConvert.DeserializeObject<List<SupplierDetails>>(sdetails); }

return countSuppliers + "Inserted";
    }
    catch (SocketException)
    {
        System.Threading.Thread.Sleep(25000);

        try
        {
            var output = GetSuppliers();
            return output;
        }
        catch (Exception ex)
        {
            var exception = new Exception(@"Exception occurred in the Sync Process while fetching the suppliers list and method name is GetSuppliers.
                                                   The Exception is " + Environment.NewLine + ex.Message);
            var message = exception.Message;
            SendMail.InsertIssue(message.Replace("'", "''"));
            return "-1";
        }

    }
    catch (Exception excp)
    {


        var exception = new Exception(@"Exception occurred in the Sync Process while fetching the suppliers list and method name is GetSuppliers.
                                                   The Exception is " + Environment.NewLine + excp);



        SendMail.InsertIssue(exception.ToString().Replace("'", "''"));

    }
    finally
    {
        if (connect != null && connect.State == ConnectionState.Open)
        { connect.Dispose(); }

    }

    return string.Empty;
}

Json返回字符串

我把你所提供的内容最简单的实现放在一起，并发现这有效：

string sdetails = "[{\"SUPPLIERID\":\"10148 \",\"SUPPLIERNAME\":\"ALLIED ELECTRONICS -LUD \",\"TNAMC\":\"ACCOUNTS RECEIVABLE \",\"TNAMB\":\" \",\"TNAME\":\"FORT WORTH \",\"TPSTC\":\"76113 - 2325\",\"TCSTE\":\"TX\",\"TCCTY\":\"USA\",\"PHONE\":\"616 - 365 - 9960 \",\"FAX\":\"6163659895 \"},{\"SUPPLIERID\":\"10159 \",\"SUPPLIERNAME\":\"ALRO STEEL CO. \",\"TNAMC\":\"P.O.BOX 30382 \",\"TNAMB\":\" \",\"TNAME\":\"LANSING \",\"TPSTC\":\"48909 - 7882\",\"TCSTE\":\"MI\",\"TCCTY\":\"USA\",\"PHONE\":\"616 - 248 - 7687 \",\"FAX\":\"6164522779 \"}]";
List<SupplierDetails> supplierslist = JsonConvert.DeserializeObject<List<SupplierDetails>>(sdetails);

您确定问题中列出的JSON字符串是sdetails中的完整答案吗？鉴于错误表明你在字符0处有错误，我怀疑你没有收到你所描述的JSON。

解析值时遇到意外的字符：c。路径＆＃39;＆＃39;，第0行，第0位
