Overloads

ViewDataDictionary<TModel>(ViewDataDictionary)	Initializes a new instance of the ViewDataDictionary<TModel> class based in part on an existing ViewDataDictionary instance.
ViewDataDictionary<TModel>(IModelMetadataProvider, ModelStateDictionary)	Initializes a new instance of the ViewDataDictionary<TModel> class.
ViewDataDictionary<TModel>(ViewDataDictionary, Object)	Initializes a new instance of the ViewDataDictionary<TModel> class based in part on an existing ViewDataDictionary instance. This constructor is careful to avoid exceptions SetModel(Object) may throw when model is null.

ViewDataDictionary<TModel>(ViewDataDictionary)

Initializes a new instance of the ViewDataDictionary<TModel> class based in part on an existing ViewDataDictionary instance.

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

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

new Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary<'Model> : Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary -> Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary<'Model>

Public Sub New (source As ViewDataDictionary)

Parameters

source

ViewDataDictionary

ViewDataDictionary instance to copy initial values from.

Remarks

For use when copying a ViewDataDictionary instance and TModel is known but Model should be copied from the existing instance e.g. when copying from a base ViewDataDictionary instance to a ViewDataDictionary<TModel> instance.

This constructor may throw if source.Model is non-null and incompatible with TModel. Pass model: null to ViewDataDictionary<TModel>(ViewDataDictionary, Object) to ignore source.Model.

ViewDataDictionary<TModel>(IModelMetadataProvider, ModelStateDictionary)

Initializes a new instance of the ViewDataDictionary<TModel> class.

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<'Model> : Microsoft.AspNetCore.Mvc.ModelBinding.IModelMetadataProvider * Microsoft.AspNetCore.Mvc.ModelBinding.ModelStateDictionary -> Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary<'Model>

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

Parameters

metadataProvider

IModelMetadataProvider
