Constructors

	Name	Description
	MemberInfo	Initializes a new instance of the MemberInfo class.

Properties

	Name	Description
	DeclaringType	Gets the class that declares this member.
	MemberType	When overridden in a derived class, gets a MemberTypes value indicating the type of the member — method, constructor, event, and so on.
	MetadataToken	Gets a value that identifies a metadata element.
	Module	Gets the module in which the type that declares the member represented by the current MemberInfo is defined.
	Name	Gets the name of the current member.
	ReflectedType	Gets the class object that was used to obtain this instance of MemberInfo.

Methods

	Name	Description
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetCustomAttributes(Boolean)	When overridden in a derived class, returns an array of all custom attributes applied to this member.
	GetCustomAttributes(Type, Boolean)	When overridden in a derived class, returns an array of custom attributes applied to this member and identified by Type.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDefined	When overridden in a derived class, indicates whether one or more attributes of the specified type or of its derived types is applied to this member.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

The MemberInfo class is the abstract base class for classes used to obtain information about all members of a class (constructors, events, fields, methods, and properties).

This class introduces the basic functionality that all members provide.

In Silverlight-based applications, you cannot derive new types from MemberInfo.

Examples

The following example displays the member name and type of a specified class.

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

Imports System.Reflection

Class Example

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock) 

      ' Get the Type and MemberInfo.
      Dim MyType As Type = GetType(System.Threading.Thread)

      ' Display the MemberType and the member.
      outputBlock.Text &= String.Format("There are {0} members in {1}:" & vbLf, _
         MyType.GetMembers().Length, MyType.FullName)

      For Each mi As MemberInfo In MyType.GetMembers()
         outputBlock.Text &= String.Format("  {0} - {1}" & vbLf, _
            mi.MemberType, mi)
      Next 

   End Sub
End Class

using System;
using System.Reflection;

class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      // Get the Type and MemberInfo.
      Type MyType = typeof(System.Threading.Thread);

      // Display the MemberType and the member.
      outputBlock.Text += String.Format("There are {0} members in {1}:\n", 
         MyType.GetMembers().Length, MyType.FullName);

      foreach (MemberInfo mi in MyType.GetMembers())
      {
         outputBlock.Text += String.Format("  {0} - {1}\n",
            mi.MemberType, mi);
      }
   }
}
