ViewDataDictionary(ViewDataDictionary)

Source:: ViewDataDictionary.cs

Source:: ViewDataDictionary.cs

Source:: ViewDataDictionary.cs

完全基于现有实例 ViewDataDictionary 初始化类的新实例。

public:
 ViewDataDictionary(Microsoft::AspNetCore::Mvc::ViewFeatures::ViewDataDictionary ^ source);

public ViewDataDictionary (Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary source);

new Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary : Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary -> Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary

Public Sub New (source As ViewDataDictionary)

参数

source: ViewDataDictionary

ViewDataDictionary 要从中复制初始值的实例。

注解

用于复制ViewDataDictionary实例和声明Type Model的不会更改，例如从ViewDataDictionary<TModel>实例复制到基ViewDataDictionary实例时。

不应将此构造函数用于可能设置为与声明类型source不兼容的值的任何上下文Model中。

ViewDataDictionary(IModelMetadataProvider, ModelStateDictionary)

Source:: ViewDataDictionary.cs

Source:: ViewDataDictionary.cs

Source:: ViewDataDictionary.cs

初始化 ViewDataDictionary 类的新实例。

public:
 ViewDataDictionary(Microsoft::AspNetCore::Mvc::ModelBinding::IModelMetadataProvider ^ metadataProvider, Microsoft::AspNetCore::Mvc::ModelBinding::ModelStateDictionary ^ modelState);

public ViewDataDictionary (Microsoft.AspNetCore.Mvc.ModelBinding.IModelMetadataProvider metadataProvider, Microsoft.AspNetCore.Mvc.ModelBinding.ModelStateDictionary modelState);

new Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary : Microsoft.AspNetCore.Mvc.ModelBinding.IModelMetadataProvider * Microsoft.AspNetCore.Mvc.ModelBinding.ModelStateDictionary -> Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary

Public Sub New (metadataProvider As IModelMetadataProvider, modelState As ModelStateDictionary)

参数

metadataProvider: IModelMetadataProvider

IModelMetadataProvider 用于创建 ModelExplorer 实例的实例。

modelState: ModelStateDictionary

ModelStateDictionary 此范围的实例。

注解

在为新的顶级范围创建 ViewDataDictionary 时使用。

ViewDataDictionary(IModelMetadataProvider, Type)

Source:: ViewDataDictionary.cs

Source:: ViewDataDictionary.cs

初始化 ViewDataDictionary 类的新实例。

protected:
 ViewDataDictionary(Microsoft::AspNetCore::Mvc::ModelBinding::IModelMetadataProvider ^ metadataProvider, Type ^ declaredModelType);

protected ViewDataDictionary (Microsoft.AspNetCore.Mvc.ModelBinding.IModelMetadataProvider metadataProvider, Type declaredModelType);

new Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary : Microsoft.AspNetCore.Mvc.ModelBinding.IModelMetadataProvider * Type -> Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary

Protected Sub New (metadataProvider As IModelMetadataProvider, declaredModelType As Type)

参数

metadataProvider: IModelMetadataProvider

declaredModelType: Type

Type预期值的。Model 用于设置 ModelMetadata。

注解

在为新的顶级范围创建派生 ViewDataDictionary 时使用。

Protected Sub New (source As ViewDataDictionary, declaredModelType As Type)

参数

source: ViewDataDictionary

ViewDataDictionary 要从中复制初始值的实例。

declaredModelType: Type

Type预期值的。Model 用于设置 ModelMetadata。

注解

在复制 ViewDataDictionary 实例和声明 Model Type 的新实例时使用，但 Model 应从现有实例复制，例如从基 ViewDataDictionary 实例复制到 ViewDataDictionary<TModel> 实例时。

如果为非null 且与不兼容，则此构造函数可能throw。declaredModelTypesource.Model 将传递给 model: null 以 ViewDataDictionary(ViewDataDictionary, Object, Type) 忽略 source.Model。
