如何在构造函数中初始化IDictionary?

new Dictionary<int, StudentName>()
{
    { 111, new StudentName {FirstName="Sachin", LastName="Karnik", ID=211}},
    { 112, new StudentName {FirstName="Dina", LastName="Salimzianova", ID=317}},
    { 113, new StudentName {FirstName="Andy", LastName="Ruth", ID=198}}
};

下面的博客文章有一个助手方法,可以从匿名类型创建字典对象。

void CreateADictionaryFromAnonymousType() 
   { 
       var dictionary = MakeDictionary(new {Name="Roy",Country="Israel"}); 
       Console.WriteLine(dictionary["Name"]); 
   }

private IDictionary MakeDictionary(object withProperties) 
   { 
       IDictionary dic = new Dictionary<string, object>(); 
       var properties = 
           System.ComponentModel.TypeDescriptor.GetProperties(withProperties); 
       foreach (PropertyDescriptor property in properties) 
       { 
           dic.Add(property.Name,property.GetValue(withProperties)); 
       } 
       return dic; 
   }

如果您引用的是Attributes属性,那么setter是私有的,因此不能在对象初始值设定项中设置它。

初始化TagBuilder后,您应该能够使用 tr.Attributes.Add(key,value) .
