            return JsonConvert.SerializeObject(obj);
        }

在上面的代码中，一个提到的javascript函数和C#webmethod的ajax调用不起作用，没有显示任何错误，也没有达到断点。请帮助我，提前感谢

但是上面的代码使用了5个参数，但不起作用，并且没有显示将超过10个参数传递给ajax调用的任何错误

请帮帮我。。。。。。。。。。

您能为查询字符串参数添加模型吗

public class ProjectModel
    {
        public int Id { get; set; }
        public string CompanyCode { get; set; }
        public string ProjectName { get; set; }
        public string ProjectDescription { get; set; }
        public string ProjectType { get; set; }
        public string LocationSite { get; set; }
        public string Client { get; set; }
        public string Latitude { get; set; }
        public string Longitude { get; set; }
        public string Status { get; set; }
        public string FirstLevelApprover { get; set; }
        public string SecondLevelApprover { get; set; }
        public string ThirdLevelApprover { get; set; }
        public string userComment { get; set; }
        public string CrudType { get; set; }
    }

动作法中的传递模型

[WebMethod]
public static string SaveAndUpdateProject(ProjectModel model)
{
// your business logic
// you can access model properties by model.Id, model.CompanyCode
}

另外，在ajax方法中，您需要更改obj对象

var model= new Object();  
model.Id = $('#HdxtProjectId').val();
model.CompanyCode = $('#ddlCompanyPrm').val();
model.ProjectName = $('#txtProjectnamePrm').val();
// rest of the properties

在Ajax方法中，将数据更新为：

data: JSON.stringify(model),

将error函数添加到Ajax调用中以查看可能的错误问题是您的Webmethod需要querystring参数，而您正在发送一个对象。因此，路由从未被命中。下面的Alpesh Vaghela的回答应该可以。另外，字符串化对象的行应该是

JSON.stringify（obj）

正如您之前构建的那样。将error函数添加到Ajax调用中以查看可能的错误问题在于您的Webmethod需要querystring参数，而您正在发送一个对象。因此，路由从未命中。下面的Alpesh Vaghela的答案应该有效。同时，字符串化对象的行也应该有效只需将JSON.stringify（obj）设置为您之前已经构建的。ProjectMaster.aspx/SaveAndUpdateProject:1加载资源失败：服务器响应状态为500（内部服务器错误）ProjectMaster.aspx/SaveAndUpdateProject:1加载资源失败：服务器响应状态为500（内部服务器错误）
