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.

Note:
To run this example, see Building Examples That Use a Demo Method and a TextBlock Control.

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
