CodePudding user response:

The two number is random, so don't know the comboBox index, cannot use RemoveAt grammar,

CodePudding user response:

public void Remove (object value)
{
The RemoveAt (IndexOf (value));
}

CodePudding user response:

If the insert is AddString (2) use the Remove are removed (2), if the AddString (" 2 ") is the Remove (" 2 "), Remove the parameter is the AddString () parameters
