    AndFilterExpression Class
    In This Topic
    Represents a logical AND filter expression, which states that an item must match all the specified child filters in order to be included.
    Syntax
    'Declaration
 
<DebuggerDisplayAttribute("FilterBy = {DebuggerDisplayString}")>
<ContentPropertyAttribute("ChildExpressions")>
Public NotInheritable Class AndFilterExpression 
   Inherits FilterExpressionOperator
    'Usage
 
Dim instance As AndFilterExpression
    [DebuggerDisplay("FilterBy = {DebuggerDisplayString}")]
[ContentProperty("ChildExpressions")]
public sealed class AndFilterExpression : FilterExpressionOperator
    Remarks
    Once the filter expression has been created, it is considered "frozen" and its values can no longer be modified.
