客户端调用web service时报错，很奇怪，请帮我看看！

[gshope]

web service程序没问题，生成的*.asmx文件正常。
在客户端程序添加web引用也成功了，但是在调用代理类的时候报错：
行 28：
行 29： /// <remarks/>
行 30： public Service1() {
行 31： this.Url= "http://192.168.30.48/aspnet/aspnet/Service1.asmx";
行 32： }
这是代理类的构造函数部分的代码，其中30行报错，信息如下：
System.IO.FileNotFoundException: 找不到文件或程序集名称“xf6jygsy.dll”，或找不到它的一个依赖项。

而且奇怪的是，xf6jygsy.dll这个文件名每次报错时还都不一样，怎么回事？？

[gshope]

说明一下，web service程序和客户端程序都在本地机上。这样添加web引用有什么不同吗？

[lovewangj]

Web Service放在哪里都一样的，你先在机器里面查找一下这个dll在什么地方。

你可以直接写地址来调用呀：
url = "http://localhost/netclass/Modules/ClassBrowser/GetContent.asmx/GetContent";
postRequest = "nItemID=" + itemId;
xhttp.Open("POST", url, false);
xhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhttp.setRequestHeader("Content-Length", postRequest.length);
xhttp.send(postRequest);
doc.load(xhttp.ResponseXML);
s = doc.selectSingleNode("//string").text;
var ovc = document.getElementById("_ctl3_ContentArea");
ovc.innerHTML = s;

添加web引用对于web 服务在哪是一样的

[cityhunter172]

你应该在VS.Net的“解决方案资源管理器”里右击“引用”->“添加Web引用”（如http://cityhunter.meibu.com/Service1.asmx）

引用方法时，通过对象调用

com.meibu.cityhunter.Service1 sv =new com.meibu.cityhunter.Service1();
this.TextBox1.Text = sv.HelloWorld();

需注意的是如有防火墙，要充许 aspnet_wp.exe 访问网络

没有一个回复是真正有意义的，哎！

try it:uninstalling the .NET Framework and reinstalling it.

This is a security issue; the ASPNET user was not able to write to the specified directory.

[saucer]

have you tried to change

userName in <processModel> in machine.config to "SYSTEM"

?

if nothing works, I would agree with cyp503(谁怕？一蓑烟雨任平生) , try to reinstall .NET

你能确认你的ASMX没有问题（使用ASMX的URL直接访问）？

如果真的没有问题，你应该……（对了，你是在什么环境调用WEBSERVICE？）。

[gshope]

直接访问asmx没问题，web service 和客户端程序在同一机器上，是win2K server

[saucer]

try to give ASPNET full access to C:\WINNT\Microsoft.NET\Framework\v1.0.3705\Temporary ASP.NET Files

or change

userName in <processModel> in machine.config to "SYSTEM"

asmx文件直接访问没问题，但是在测试它的方法时报错，信息如下：
System.IO.FileNotFoundException: 找不到文件或程序集名称“lfpbf0_o.dll”，或找不到它的一个依赖项。

另外，我把C:\WINNT\Microsoft.NET\Framework\v1.0.3705\Temporary ASP.NET Files
和c:\winnt\temp两个目录都设置成everyone的完全控制权限，错误还是一样！
