Service contract:

[OperationContract]
void InsertEmployeeData(EmployeeDetail empName);

Method definition:

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

Call from client:

EmployeeDetail data = new EmployeeDetail();
data.EmployeeName = collection.Get("EmployeeName");
data.Designation = collection.Get("Designation");
data.EmailID = collection.Get("EmailID");
data.City = collection.Get("City");
data.State = collection.Get("State");
data.Country = collection.Get("Country");               
data.Photo = ConvertImage(@"E:\Anish\S6M0.png");
conn.InsertEmployeeData(data);

while trying to pass EmployeeDetail object with photo as byte array to wcf service gets exception. Image with 6kb gets inserted .but image with size 50 kb throws exception:

The remote server returned an unexpected response: (400) Bad Request.

But i need to do with image size up to 2 mb.

尝试在您的web.config文件中启用调试。这将为您提供更有意义的错误消息，而不仅仅是(400) Bad Request.

<configuration>在您的标签下添加此 XML 片段：

<system.web>
  <customErrors mode="Off"/>
  <trace enabled="true" localOnly="false"> 
  <compilation debug="true"/>
</system.web>

然后再试一次。

完成后不要忘记删除调试标志，因为在生产环境中使用它们是一个安全漏洞。
