示例1: EnsureParentPosition
/// <summary>
/// Sets parentPosition to be a valid TextPointer in the parent document. This could either
/// be the textPosition passed in (if its already on the parent document) or a conversion
/// of the textPosition passed in.
/// </summary>
/// <returns>whether or not parentPosition is valid and should be used</returns>

// If textPosition is on a child TextContainer, we convert it
if (textPosition.TextContainer.Highlights != this)

// This case can't be converted so return false, out parameter should not be used
if (textPosition.GetPointerContext(direction) == TextPointerContext.None)
return false;
// Turn the textPosition (which should be in the scope of a FixedDocument)
// into a position in the scope of the DocumentSequence.

}示例2: GetStaticPositionInChildContainer
/// <summary>

/// on a specified FixedDocument. If the conversion results in a pointer on a different
/// FixedDocument then we return one end of the FixedDocument (based on direction).
