    deleteSpan As Span _
) As ITextSnapshot

ITextSnapshot Delete(
    Span deleteSpan
)

ITextSnapshot^ Delete(
    Span deleteSpan
)

abstract Delete : 
        deleteSpan:Span -> ITextSnapshot

function Delete(
    deleteSpan : Span
) : ITextSnapshot

Parameters

deleteSpan
Type: Microsoft.VisualStudio.Text.Span
The span of characters to delete.

Return Value

Type: Microsoft.VisualStudio.Text.ITextSnapshot
The ITextSnapshot.

Exceptions

Exception	Condition
InvalidOperationException	A ITextEdit is currently active.
ArgumentOutOfRangeException	deleteSpan.End is greater than the length of the buffer.

Remarks

This is a shortcut for creating a new ITextEdit object, using it to delete the text, and then applying it. If the deletion fails because of a read-only region, the snapshot returned will be the same as the current snapshot of the buffer before the attempted deletion.
