C# Script Multidimensional array length


I'm retrieving some data from a DB and I load it into a multidimensional array.

The thing is, I don't always know the size of the array beforehand, so I'd like to make a function to go through all of it to find the data I'm looking for.

So far so good, except I cannot make that function without knowing the length of the array.

Is there any way to know it?

  • Hi Leandro, are you executing the Script in Test Complete or in a C# Self-Testing and/or Connected Application?


    If it is the latter then the following is pertinent in the C# Script documentation

    "3. Do not use JScript statements with and for…in and JScript operators ===, !==, >>> and >>>=. They are not supported in C#. If you use them, you will have to update your code when porting it to a C# application.

    4. In addition, these JScript objects are not currently supported in C# applications: Array, Boolean, Date, Function, Global, Math, Number, Object, RegExp, Error and String."


    If you are executing the Script in Test Complete be aware that C# Script is based on JScript therefore has no concept of multi-dimensional arrays, instead you need to use the arrays of arrays model, e.g.


    function testArray() {

      // Multi-dimensional array of arrays

      var arr = [ [ 1, 2, 3 ],

                  [ 4, 5, 6 ],

                  [ 7, 8, 9 ] ];


      // Iterate the outer array

      for( var a = 0; a < arr["length"]; a++ ) {

        // Iterate each inner array

        for( b = 0; b < arr[ a ]["length"]; b++ ) {

          Log["Message"]( arr );
