TextRange Interface

Represents a single, contiguous section of text in a text document.

Namespace:  EnvDTE
Assembly:  EnvDTE (in EnvDTE.dll)

[GuidAttribute("72767524-E3B3-43D0-BB46-BBE1D556A9FF")]
public interface TextRange

The section of text is enclosed by a pair of EditPoint objects.

TextRange objects are used when you have regular expressions with tagged subexpressions. A collection of ranges is returned, one for each matched subexpression, and their properties are read-only.

For general text manipulation, it is recommended that you instead use objects such as TextSelection or EditPoint, because the TextSelection object relates directly to the selection visible on the screen. When the selection area changes, the object's coordinates change, and vice-versa. As a result, a text selection cannot be used to represent an arbitrary range of text without disrupting that text selection.

public void TextRangeExample(_DTE dte)
{
    TextSelection ts;
    TextRanges trs;

    ts = (TextSelection)dte.ActiveDocument.Selection;
    trs = ts.TextRanges;
    MessageBox.Show (trs.Count.ToString ());
    foreach (TextRange tr in trs)
    {
        tr.StartPoint.Insert ("/*");
        tr.EndPoint.Insert ("*/");
    }
}
