Type.FilterNameIgnoreCase Field

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Represents the case-insensitive member filter used on names. This field is read-only.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Shared ReadOnly FilterNameIgnoreCase As MemberFilter
public static readonly MemberFilter FilterNameIgnoreCase

Remarks

This field holds a reference to the delegate used by the FindMembers method. The method encapsulated by this delegate takes two parameters: the first is a MemberInfo object and the second is an Object. The method determines whether the MemberInfo object matches the criteria specified by the Object. The Object is assigned a string value, which may include a trailing "*" wildcard character. Only wildcard end string matching is supported.

For example, the Object may be assigned the value "ByTe*". In that case, when the FilterName delegate is invoked, it will return true only if the method represented by the MemberInfo object has a name that begins with "byte", ignoring case.

Examples

The following example gets the MemberFilter delegate, passes it as a parameter to the FindMembers method, and displays the methods and their attributes of the String class that begin with the letter "c", disregarding the case.

Imports System.Reflection
Imports System.Security

Public Class Example
    Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
        Dim myFilter As MemberFilter = Type.FilterNameIgnoreCase
        Dim myType As Type = GetType(System.String)

        Dim myMemberinfo1 As MemberInfo() = _
            myType.FindMembers(MemberTypes.Property Or MemberTypes.Method, _
                BindingFlags.Public Or BindingFlags.Static Or BindingFlags.Instance, _
                myFilter, "c*")

        For Each mi As MemberInfo In myMemberinfo1
            outputBlock.Text &= mi.ToString() & " is a " & _
                mi.MemberType.ToString() & vbLf
        Next 
    End Sub 
End Class
