how to delete an specific row/multiple array in datagridview

Question

how to delete an specific row/multiple array element inside of a datagridview? i have this code

 

private void btnRemoveDamage_Click(object sender, EventArgs e)

{

txtDamageCode.Text = Interaction.InputBox("Enter damage code (separated by comma)", String.Empty, dmgList.Text, -1, -1);

string[]addDMG = txtDamageCode.Text.Split(',');

List add = new List();

for (int z = 0; z < addDMG.Length; z++)

{

string[] dmgdesc = new string[] { inGateRepo.GetDamageDescription(addDMG[z]) };

for (int x = 0; x < dmgdesc.Length; x++)

{

getDamage getdmg = new getDamage();

string[] dam = dmgdesc[x].Trim().Split('|');

for (int y = 0; y < dam.Length; y++)

{

switch (y)

{

case 0:

getdmg.damageCode = dam[y];

break;

case 1:

getdmg.damageDesc = dam[y];

break;

}

}

add.Add(getdmg);

}

}

dmgList.DataSource = add;

}

 

it works like this. i have 3 array with description in my datagridview but if i want 2 is the only one remain then i just type 2 and the rest will not be included

 

1|some description

2|some description

3|some description

how can i remove it like this  users.DeleteUser((GetAllUsers)lstUsers.CurrentRow.DataBoundItem);

i just want to delete only the current row not to type it again.
