I have an Array .I want to remove the element which is matching the Condition..

C#

for (var i = 0; i < DQuestions.length; i++)
                {
                    //for(j=0;j<rules[i].length;j++)
                    {
                        if ((DQuestions[i][0] == Id))
                        {
                            alert(DQuestions[i][1]);

                            var idx = DQuestions.indexOf(DQuestions[i]); // Find the index
              alert('idx '+idx);
              if(idx!=-1)
              {
                 DQuestions.splice(idx, 1);

                        }
                        else
                        {
                        alert('I doonno');
              }
                        }
                    }
                }
                for (i = 0; i < DQuestions.length; i++)
                    {
                       alert(DQuestions[i][0]+" AFtR"+DQuestions[i][1]);
            }

I add with the following condition

C#

for (var i = 0; i < n.length; i++)
                                {
                                alert(" LEngth "+DQuestions.length);
                                DQuestions[DQuestions.length]=new Array(Id,n[i]);
                                //  DQuestions.unshift(n[i]);
                                alert('DQuestions.length '+ DQuestions.length);
                                alert(DQuestions[i][0]+" "+DQuestions[i][1]);
                                }

It is of the type

C#

var array = new array (a,b);

I am unable to delete The value from array and out of 3 values only 2 get deleted and 2 indexed value remains undeleted

I might not be the most efficient way of doing it but what I do is use lists

so what i do is

C#

TypeOfArray[] myarray = new TypeOfArray[];
//load styuuf in array

List<typeofarray> toKeep = new List<typeofarray>

foreach(TypeofArray element in myArray)
{
     if(!removeConditionMet){
            toKeep.Add(element);

      }
 
}
myArray = toKeep.ToArray();

Hope this helps
