FilterNameIgnoreCase Field

Type.FilterNameIgnoreCase Field

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

[Visual Basic]
Public Shared ReadOnly FilterNameIgnoreCase As MemberFilter
[C#]
public static readonly MemberFilter FilterNameIgnoreCase;
[C++]
public: static MemberFilter* FilterNameIgnoreCase;
[JScript]
public static var FilterNameIgnoreCase : MemberFilter;

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.

Example

[Visual Basic, C#, C++] 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.
