Question

我创建了一个WCF服务，用于将图像保存为字节数组。以下是合同，实施和要点详情

合同

  [OperationContract]
        void InsertEmployeeData(EmployeeDetail empName);

实施

 public void InsertEmployeeData(EmployeeDetail empName)
        {
            ctx.EmployeeDetails.AddObject(empName);
            ctx.SaveChanges();
        }

当我尝试保存低于15 kb时，我可以成功保存。当上传超过15 kb时，我得到异常远程服务器返回了意外响应：（400）错误请求我该如何解决这个问题错误？

如果您在IIS上托管服务，那么请求长度限制为15 kb是一个很好的变化。尝试更改IIS设置

<httpRuntime maxRequestLength="25000" />

将请求长度更改为最大值。您要上传的文件大小。

例外：WCF服务在将图像作为字节数组保存到数据库时抛出Bad Request
