Copy
C#
double GetLengthInput(Document document, String userInputLength)
{
double dParsedLength = 0;
Units units = document.GetUnits();
// try to parse a user entered string (i.e. 100 mm, 1'6")
bool parsed = UnitFormatUtils.TryParse(units, UnitType.UT_Length, userInputLength, out dParsedLength);
if (parsed == true)
{
string msg = string.Format("User Input: {0}\r\nParsed value: {1}", userInputLength, dParsedLength);
TaskDialog.Show("Parsed Data", msg);
}
return dParsedLength;
}

Dim parsed As Boolean = UnitFormatUtils.TryParse(units, UnitType.UT_Length, userInputLength, dParsedLength)
