示例1: GetTextLocation
TextLocation GetTextLocation(TextBox textBox, int offset)
{
int line = textBox.GetLineFromCharIndex(offset);
int col = offset - textBox.GetFirstCharIndexFromLine(line);
return new TextLocation(line + 1, col + 1);
}示例2: GetOffset
int GetOffset(TextBox textBox, AstLocation location)
{
return textBox.GetFirstCharIndexFromLine(location.Line - 1) + location.Column - 1;
}示例3: GetOffset
int GetOffset(TextBox textBox, TextLocation location)
{
// TextBox uses 0-based coordinates, TextLocation is 1-based
return textBox.GetFirstCharIndexFromLine(location.Line - 1) + location.Column - 1;

// StreamWriter is used to write the SQL.
