Description
Use the FindLast method to find a substring in the input string. If the input string holds several occurrences of the substring, the method returns the position of the last matching substring.
Declaration
aqString.FindLast(InputString, SubString, CaseSensitive)
| InputString | [in] | Required | String | |
| SubString | [in] | Required | String | |
| CaseSensitive | [in] | Optional | Boolean | Default value: True |
| Result | Integer | |||
Applies To
The method is applied to the following object:
Parameters
The method has the following parameters:
InputString
Specifies the string where a substring will be sought for.
SubString
Specifies the sought-for string.
CaseSensitive
Specifies whether the comparison should be case-sensitive or not.
Result Value
If the substring was found, the method returns the zero-based index of the last matching substring. Otherwise, the method returns -1.
Example
The code below searches for the last occurrence of the 'lex' substring within the 'Dura lex, sed lex' string.
JavaScript, JScript
{
var aString, aSubString, Res;
aString = "Dura lex, sed lex";
aSubString = "lex";
Res = aqString.FindLast(aString,aSubString);
if (Res != -1)
Log.Message("The last occurrence of the substring '" + aSubString + "' within the string '" + aString + "' is at position " + Res)
else
Log.Message("There are no occurrences of the substring '" + aSubString + "' in the '" + aString + "'")
}
// Result:
// The last occurrence of the 'lex' substring within the 'Dura lex, sed lex' string is at position 14

Else

End If
End Sub
' Result:

DelphiScript

end;
// Result:
// The last occurrence of the 'lex' substring within the 'Dura lex, sed lex' string is at position 14
C++Script, C#Script
{
var aString = "Dura lex, sed lex";
var aSubString = "lex";
var Res = aqString["FindLast"](aString,aSubString);
