Syntax
'宣言
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.
