Items - Add / Remove


Accessing Elements

Another method you may use frequently is the GetValue method.

'Will return the value of the 9th element if there is one.

int myValue = myArray.GetValue(9); 

We can access an array element by passing the item index to the array

int myValue = myArray[0]; 
int myValue = myArray[1];

string[] myArray; 
string[] myArray = new string[3];
myArray[0] = 5;
myArray[1] = 10;

GetValue Method


Clear method

You can clear a portion of an array with the Clear method.

System.Array.Clear(ArrayName, Index, Length) 

ArrayName - The array you want to clear
Index - The starting index of the range of elements to clear
Length - The number of elements to clear

clsComponent gaComponentArray(10, 20) 
System.Array.Clear(gaComponentArray, 0, (10 + 1) * (20 + 1))

Another feature is the Clear method. So, if you clear element 2 for instance and you try referencing its length property afterward, you are going to raise a null reference exception.

Array.Clear(aiArrayIntegers, 0, 1)
