一个简单的WCF示例服务 [英] A Simple Sample WCF Service

问题描述

我关注了您关于代码项目的文章，并遇到以下问题.

WCF服务主机对话框显示
1)存储BookService错误，没有元数据.有关更多信息，请参见* 1.
2)WcfServiceLibrary1启动没有错误.
2)代码在Form1.cs中的第58行停止.请参阅* 2.如果我将SampleDB.xml文件放在c:\ windows \ system32 \ inetsrv \中，它将起作用.
TIA
约翰

Hi,
I followed your article on code project and get the following issues.

THE WCF Service Host dialog box shows
1) Store BookService Error with no metadata. See *1 for additional info.
2) WcfServiceLibrary1 started with not errors.
2) The code stops in Form1.cs at line 58. See *2. If I put the SampleDB.xml file in c:\windows\system32\inetsrv\, it works.
TIA
John

推荐答案

为更清晰起见，您需要共享代码.

在分析给定的两个错误时，建议的根本原因如下:

1.尝试将安全模式从传输"更改为无".或验证http连接的安全性部分.

2.看来您的WCF服务需要"c:\ windows \ system32 \ inetsrv \ SampleDB.xml"文件，该文件已丢失.

For better clarity, you need to share the code.

On analysing the given two errors, the suggested root cause as below:

1. Try changing the security mode from Transport to none. Or verify the security part of http connection.

2. Looks like your WCF service needs ''c:\windows\system32\inetsrv\SampleDB.xml'' file, which is missing.
