Count of types from datagridview

Question

I have a datagrid view like this:

private void Form1_Load(object sender, EventArgs e)

{

AddRowsInDatagridView(0,"Rohim", "Apple", "3", "2");

AddRowsInDatagridView(1,"Karim", "Banana", "", "3");

AddRowsInDatagridView(2,"Karim", "Guava", "5", "7");

AddRowsInDatagridView(3,"Rohim", "Coconut", "6", "8");

AddRowsInDatagridView(4,"Karim", "Banana", "3", "5");

AddRowsInDatagridView(5,"Rohim", "Jackfruit", "2", "9");

AddRowsInDatagridView(6,"Rohim", "Apple", "1", "12");

AddRowsInDatagridView(7, "Rohim", "Apple", "1", "12");

AddRowsInDatagridView(8, "Karim", "Guava", "5", "7");

AddRowsInDatagridView(7, "Rohim", "Palm", "1", "12");

AddRowsInDatagridView(8, "Shovan", "Date", "5", "7");

AddRowsInDatagridView(9, "Karim", "Banana", "3", "5");

}

 

Expected:

Rohim has = 4 types of fruit.

Karim has = 2 types of fruit.

Shovan has = 1 type of fruits.
