Filter ExpressionΒΆ

This is the “top-level” item for the definition of a filter expression. One or more expressions must be added as children.

Adding a filter expression as a child of another filter expression gives you the ability to build more complex expressions. For example, you can build an expression that includes contacts whose email address contains “” or “” and whose region is “Europe”.


Filter expression items are converted into instances of the type Microsoft.Xrm.Sdk.Query.FilterExpression. For more information, see
