Parameters

• textView
  Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextView

  An IVsTextView object that represents the view containing the source to examine.

• line
  Type: System.Int32

  The line number in the source.

• col
  Type: System.Int32

  The offset on the line.

• span
  Type: Microsoft.VisualStudio.TextManager.Interop.TextSpan%

  [out] A TextSpan object containing the span of the enclosing paired elements.

Remarks

A matching pair of elements is any supported language element such as { and }, ( and ), [ and ], or < and >. If the given location lies between two paired elements, the returned span goes from the first or opening paired element to the second or closing paired element and includes the paired elements.

The base method executes a parse of the source with the reason MatchBraces and starting at the given location. It then examines the list of matching braces to find the innermost containing pair. The base method also examines any matching triplets and treats them as containing pairs.
