Constructor & Destructor Documentation

◆ AttributeUsageAttribute()

System.AttributeUsageAttribute.AttributeUsageAttribute ( AttributeTargets validOn )

Initializes a new instance of the T:System.AttributeUsageAttribute class with the specified list of T:System.AttributeTargets, the P:System.AttributeUsageAttribute.AllowMultiple value, and the P:System.AttributeUsageAttribute.Inherited value.

Parameters

validOn The set of values combined using a bitwise OR operation to indicate which program elements are valid.

Definition at line 71 of file AttributeUsageAttribute.cs.

Property Documentation

◆ AllowMultiple

bool System.AttributeUsageAttribute.AllowMultiple

getset

Gets or sets a Boolean value indicating whether more than one instance of the indicated attribute can be specified for a single program element.

Returns: true if more than one instance is allowed to be specified; otherwise, false. The default is false.

Definition at line 37 of file AttributeUsageAttribute.cs.

◆ Inherited

bool System.AttributeUsageAttribute.Inherited

getset

Gets or sets a T:System.Boolean value that determines whether the indicated attribute is inherited by derived classes and overriding members.

Returns: true if the attribute can be inherited by derived classes and overriding members; otherwise, false. The default is true.

Definition at line 55 of file AttributeUsageAttribute.cs.

◆ ValidOn

AttributeTargets System.AttributeUsageAttribute.ValidOn

get

Gets a set of values identifying which program elements that the indicated attribute can be applied to.

Returns: One or several T:System.AttributeTargets values. The default is All.
