我用 C# 编写了一个 web 服务，并试图在 IIS 7.0 上托管它。考虑以下代码，此代码运行良好，可以毫无问题地托管在 IIS 7.0 上：

using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Linq;
using System.Web;
using System.Web.Services;
using VMware;

namespace vmareService
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the     following line. 
// [System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{

    [WebMethod]

    public void logintoVmware(string URL, string username, string password)
          {
        VMware.Vim.VimClient client = new VMware.Vim.VimClient();

    }

}
}

现在，如果我希望此方法返回我的会话 ID，我将代码更改为以下内容：

using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Linq;
using System.Web;
using System.Web.Services;
using VMware;

namespace vmareService
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the     following line. 
// [System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{

    [WebMethod]

    //public void logintoVmware(string URL, string username, string password)
    public VMware.Vim.UserSession logintoVmware(string URL, string username, string password)
    {
        VMware.Vim.VimClient client = new VMware.Vim.VimClient();
        VMware.Vim.UserSession session;
        session = client.Login(URL, username, password);
        return session;

    }

}
}

现在，虽然我在代码中引用了 vmware.vim.dll 并且还将该文件包含在托管在 IIS 7.0 上的文件夹中，但我收到以下错误消息：

Server Error in '/vmService' Application.

您应该确保此文件位于您的 /bin 文件夹中。如果是，那么您应该调查它的潜在依赖关系可能是什么。请记住，仅仅因为该文件存在并不意味着它的所有依赖 dll 都可用。
