TypeLibVarAttribute Class
.NET Framework 3.0
Contains the VARFLAGS that were originally imported for this field from the COM type library.
Namespace: System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)
Assembly: mscorlib (in mscorlib.dll)
'Declaration <AttributeUsageAttribute(AttributeTargets.Field, Inherited:=False)> _ <ComVisibleAttribute(True)> _ Public NotInheritable Class TypeLibVarAttribute Inherits Attribute 'Usage Dim instance As TypeLibVarAttribute
/** @attribute AttributeUsageAttribute(AttributeTargets.Field, Inherited=false) */ /** @attribute ComVisibleAttribute(true) */ public final class TypeLibVarAttribute extends Attribute
AttributeUsageAttribute(AttributeTargets.Field, Inherited=false) ComVisibleAttribute(true) public final class TypeLibVarAttribute extends Attribute
Not applicable.
The Type Library Importer (Tlbimp.exe) applies this attribute to fields.
This attribute is applied when a type library is imported and should never be changed. It is only applied when the method's VARFLAGS evaluate to non-zero. The attribute is designed to be used by tools that need to know how the original VARFLAGS were set. The common language runtime does not use this attribute.
The following example demonstrates how to get the TypeLibVarAttribute value of a field.
Imports System Imports System.Reflection Imports System.Runtime.InteropServices Module D Public Function IsHiddenField(ByVal fi As FieldInfo) As Boolean Dim FieldAttributes As Object() = fi.GetCustomAttributes(GetType(TypeLibVarAttribute), True) If FieldAttributes.Length > 0 Then Dim tlv As TypeLibVarAttribute = FieldAttributes(0) Dim flags As TypeLibVarFlags = tlv.Value Return (flags & TypeLibVarFlags.FHidden) > 0 End If Return False End Function End Module

{
Object fieldAttributes[] =
fi.GetCustomAttributes(TypeLibVarAttribute.class.ToType(), true);
if (fieldAttributes.length > 0) {
TypeLibVarAttribute tlv = (TypeLibVarAttribute)fieldAttributes[0];
TypeLibVarFlags flags = tlv.get_Value();
return Convert.ToInt32(flags & TypeLibVarFlags.FHidden) != 0;
}
return false;
} //IsHiddenField
