解析值时遇到意外字符：c。路径 ， 行 0， 位置 0

Question

当它从Visual Studio 正常运行时，我在应用程序中实现了一种方法，但是当它从任务计划程序运行时，在日志文件中收到此错误

---

System.Exception：在获取供应商列表和方法名称为 GetSuppliers 时，同步过程中发生异常。异常是 Newtonsoft.Json.JsonReaderException：解析值时遇到意外字符：C. 第 0 行，位置 0。at Newtonsoft.Json.JsonTextReader.ParseValue() at Newtonsoft.Json.JsonTextReader.ReadInternal() at Newtonsoft.Json.JsonTextReader.Read() at Newtonsoft.Json.Serialization.JsonSerializerInternalReader.ReadForType(JsonReader reader， JsonContract contract， Boolean hasConverter， Boolean inArray) at Newtonsoft.Json.Serialization

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

我把你提出的最简单的实现放在一起，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);

您确定您在问题中列出的 JSON 字符串是您在sdetails中的完整响应吗？ 鉴于错误指出您在字符 0 处有错误，我怀疑您没有收到您描述的 JSON。
