DataMappedObjectConverter.ConvertToUnderlyingRestriction Method (String, Int32, [])

Converts the specified mapped restrictions into underlying restrictions that are data source specific.

Namespace: Microsoft.VisualStudio.Data.Framework
Assembly: Microsoft.VisualStudio.Data.Framework (in Microsoft.VisualStudio.Data.Framework.dll)

Syntax

Public Function ConvertToUnderlyingRestriction ( _
    mappedTypeName As String, _
    substitutionValueIndex As Integer, _
    mappedRestrictions As Object() _
) As Object
'使用
Dim instance As DataMappedObjectConverter
Dim mappedTypeName As String
Dim substitutionValueIndex As Integer
Dim mappedRestrictions As Object()
Dim returnValue As Object

returnValue = instance.ConvertToUnderlyingRestriction(mappedTypeName, _
    substitutionValueIndex, mappedRestrictions)

public Object ConvertToUnderlyingRestriction(
    string mappedTypeName,
    int substitutionValueIndex,
    Object[] mappedRestrictions
)

public:
virtual Object^ ConvertToUnderlyingRestriction(
    String^ mappedTypeName, 
    int substitutionValueIndex, 
    array<Object^>^ mappedRestrictions
) sealed

public final function ConvertToUnderlyingRestriction(
    mappedTypeName : String, 
    substitutionValueIndex : int, 
    mappedRestrictions : Object[]
) : Object

Parameters

mappedTypeName
Type: System.String

The name of the mapped type.

substitutionValueIndex
Type: System.Int32

Index into the array of substitution values.

mappedRestrictions
Type: []

An array containing the mapped restrictions.

Return Value

Type: System.Object

The underlying restriction that is converted from the mapped restriction.

Implements

IVsDataMappedObjectConverter.ConvertToUnderlyingRestriction(String, Int32, [])

Remarks

This method is useful when the mapped object selector ([T:Microsoft.VisualStudio.Data.Services.IVsDataMappedObjectSelector)] needs to convert the mapped restrictions to the underlying restrictions to pass to the data source–specific type selector (IVsDataMappedObjectSelector.) This process is referred to as mapped selection.

This method delegates the call to the ConvertToUnderlyingRestriction method and passes a null reference (Nothing in Visual Basic) for the last parameter.
