IDictionary<TKey,TValue>用于视图数据的。

public ref class ViewDataDictionary : System::Collections::Generic::ICollection<System::Collections::Generic::KeyValuePair<System::String ^, System::Object ^>>, System::Collections::Generic::IDictionary<System::String ^, System::Object ^>, System::Collections::Generic::IEnumerable<System::Collections::Generic::KeyValuePair<System::String ^, System::Object ^>>

public class ViewDataDictionary : System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<string,object>>, System.Collections.Generic.IDictionary<string,object>, System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<string,object>>

type ViewDataDictionary = class
    interface IDictionary<string, obj>
    interface ICollection<KeyValuePair<string, obj>>
    interface seq<KeyValuePair<string, obj>>
    interface IEnumerable

type ViewDataDictionary = class
    interface ICollection<KeyValuePair<string, obj>>
    interface seq<KeyValuePair<string, obj>>
    interface IEnumerable
    interface IDictionary<string, obj>

Public Class ViewDataDictionary
Implements ICollection(Of KeyValuePair(Of String, Object)), IDictionary(Of String, Object), IEnumerable(Of KeyValuePair(Of String, Object))

继承

派生

Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary<TModel>

实现

ICollection<KeyValuePair<String,Object>> ICollection<KeyValuePair<TKey,TValue>> IDictionary<String,Object> IEnumerable<KeyValuePair<String,Object>> IEnumerable<KeyValuePair<TKey,TValue>> IEnumerable<T> IEnumerable

构造函数

ViewDataDictionary(IModelMetadataProvider, ModelStateDictionary)	初始化 ViewDataDictionary 类的新实例。
ViewDataDictionary(IModelMetadataProvider, ModelStateDictionary, Type)	初始化 ViewDataDictionary 类的新实例。
ViewDataDictionary(IModelMetadataProvider, Type)	初始化 ViewDataDictionary 类的新实例。
ViewDataDictionary(ViewDataDictionary)	ViewDataDictionary完全基于现有实例初始化类的新实例。
ViewDataDictionary(ViewDataDictionary, Object, Type)	ViewDataDictionary基于现有实例的部分初始化类的新实例。 SetModel(Object)当 model 为null时，此构造函数将小心避免可能引发异常。
ViewDataDictionary(ViewDataDictionary, Type)	ViewDataDictionary基于现有实例的部分初始化类的新实例。

属性

Count	Gets the number of elements contained in the ICollection<T>.
IsReadOnly	Gets a value indicating whether the ICollection<T> is read-only.
Item[String]	Gets or sets the element with the specified key.
Keys	Gets an ICollection<T> containing the keys of the IDictionary<TKey,TValue>.
Model	获取或设置当前模型。
ModelExplorer	获取或设置 ModelExplorer 的 Model。
ModelMetadata	获取 ModelMetadata 表达式的， Model 如果) 为非null ，则为 (; 否则为 Type 。
ModelState	获取 ModelStateDictionary。
TemplateInfo	获取 TemplateInfo。
Values	Gets an ICollection<T> containing the values in the IDictionary<TKey,TValue>.

方法

Add(KeyValuePair<String,Object>)	Adds an item to the ICollection<T>.
Add(String, Object)	Adds an element with the provided key and value to the IDictionary<TKey,TValue>.
Clear()	Removes all items from the ICollection<T>.
Contains(KeyValuePair<String,Object>)	Determines whether the ICollection<T> contains a specific value.
ContainsKey(String)	Determines whether the IDictionary<TKey,TValue> contains an element with the specified key.
CopyTo(KeyValuePair<String,Object>[], Int32)	Copies the elements of the ICollection<T> to an Array, starting at a particular Array index.
Eval(String)	获取此中命名的的值 expression ViewDataDictionary 。
Eval(String, String)	获取 expression 在此中命名的值 ViewDataDictionary ，使用给定的格式化 format 。
FormatValue(Object, String)	使用给定的格式化给定的 value format 。
GetViewDataInfo(String)	获取 ViewDataInfo expression 此中命名的 ViewDataDictionary 。
Remove(KeyValuePair<String,Object>)	Removes the first occurrence of a specific object from the ICollection<T>.
Remove(String)	Removes the element with the specified key from the IDictionary<TKey,TValue>.
SetModel(Object)	设置 ModelExplorer 以确保 Model 并 Model 反映新的 value 。
TryGetValue(String, Object)

显式接口实现

IEnumerable.GetEnumerator()	Returns an enumerator that iterates through a collection.
IEnumerable<KeyValuePair<String,Object>>.GetEnumerator()	Returns an enumerator that iterates through the collection.
