Assembly: Microsoft.VisualStudio.Text.UI (in Microsoft.VisualStudio.Text.UI.dll)

Syntax

声明
Function GetBufferPositionAtCoordinate ( _
    coordinate As Double _
) As SnapshotPoint

SnapshotPoint GetBufferPositionAtCoordinate(
    double coordinate
)

SnapshotPoint GetBufferPositionAtCoordinate(
    double coordinate
)

abstract GetBufferPositionAtCoordinate : 
        coordinate:float -> SnapshotPoint

function GetBufferPositionAtCoordinate(
    coordinate : double
) : SnapshotPoint

Parameters

coordinate
Type: System.Double
The scrollbar coordinate.

Return Value

Type: Microsoft.VisualStudio.Text.SnapshotPoint
The corresponding buffer position.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	coordinate is NaN, less than 0.0 or greater than Maximum.

Remarks

Different buffer positions can have the same scroll bar coordinates. This method is guaranteed only to be consistent: it returns the same position for the same coordinate. The exact character returned depends on the implementation of the scroll map. It is generally the first character on the line.
