视图数据的 A IDictionary<TKey,TValue> 。

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

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

继承: Object

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)	完全基于现有实例初始化类的新实例 ViewDataDictionary 。
ViewDataDictionary(ViewDataDictionary, Object, Type)	基于现有实例的一部分初始化类的新实例 ViewDataDictionary 。此构造函数小心翼翼，以避免当`为 null` 时`model`可能会引发异常SetModel(Object)。
ViewDataDictionary(ViewDataDictionary, Type)	基于现有实例的一部分初始化类的新实例 ViewDataDictionary 。

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、 Model 非 `null`) 或声明 Type的表达式 (。
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)	获取在此ViewDataDictionary名称中命名`expression`的值。
Eval(String, String)	获取采用给定`format`格式的命名ViewDataDictionary`expression`值。
FormatValue(Object, String)	使用给定的给定`valueformat`格式。
GetViewDataInfo(String)	获取ViewDataInfo此ViewDataDictionary名称`expression`。
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)	设置为 ModelExplorer 确保 Model 并 Model 反映新 `value`。
TryGetValue(String, Object)	System.Object.TryGetValue(System.String,System.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.
