我正在开发我的第一个 MVC 4 应用程序,遵循 Asp.net 上的 MVC First Web API 教程。我保留了相同的名称,但更改了模型和控制器代码。这是我的模型:
public class Product
{
public string SID { get; set; }
public string name { get; set; }
public string givenName { get; set; }
public string sn { get; set; }
public string mail { get; set; }
public string telephoneNumber { get; set; }
public string mobile { get; set; }
public string otherMobile { get; set; }
public string title { get; set; }
public string Manager { get; set; }
public DateTime whenChanged { get; set; }
}
public class ProductModel
{
public ProductModel()
{
ProductList = new List<Product>();
}
public IList<Product> ProductList { get; set; }
}
这是我的 API 控制器:
public class ProductsController : ApiController
{
ProductModel products = new ProductModel();
public IEnumerable<Product> GetAD()
{
DirectoryEntry domainRoot = new DirectoryEntry(LDAP_server);
DirectorySearcher searcher = new DirectorySearcher(searchStr);
SearchResultCollection results = searcher.FindAll();
foreach (SearchResult srchResult in results)
{
DirectoryEntry dirEntry = srchResult.GetDirectoryEntry();
if (dirEntry.Properties["givenName"].Value != null && dirEntry.Properties["sn"].Value != null && !dirEntry.Parent.Name.Contains("Terminated"))
{
products.ProductList.Add(new Product()
{
SID = dirEntry.Properties["sid"].Value.ToString(),
name = dirEntry.Properties["name"].Value.ToString(),
givenName = dirEntry.Properties["givenName"].Value.ToString(),
sn = dirEntry.Properties["sn"].Value.ToString(),
mail = dirEntry.Properties["mail"].Value.ToString(),
telephoneNumber = dirEntry.Properties["telephoneNumber"].Value.ToString(),
mobile = dirEntry.Properties["mobile"].Value.ToString(),
otherMobile = dirEntry.Properties["otherMobile"].Value.ToString(),
title = dirEntry.Properties["title"].Value.ToString(),
Manager = dirEntry.Properties["Manager"].Value.ToString(),
whenChanged = Convert.ToDateTime(dirEntry.Properties["whenChanged"].Value.ToString()),
});
}
}
return products.ProductList;
}
}
我在 'products.ProductList.Add(new Product()' 上收到 NullException,我是否遗漏了一些简单的东西?请原谅我的编码,因为我只是想启动并运行它,谢谢。
