在运行时将web控件添加到asp.net表中

我想在运行时以定时间隔将asp.net文本web控件添加到表中。控件将从数组类的实例中获取静态值。

我不是OOP爱好者，但据我所知，我需要声明一次这个类，然后继续引用它存储的值，因为我需要这些值来为web控件提供文本值。

以下是我不断抛出的null引用异常，尽管我不仅将类初始化为数组，还将类的数组中的每个项初始化。

为什么？

编辑：

以下是类声明和初始化函数：

public class Names
{
    String name = ""; public String Name { get { return name; } set { name = value; } }
    Byte name_id = 0; public Byte NameID { get { return name_id; } set { name_id = value; } }
    Decimal point = 0; public Decimal Point { get { return point; } set { point = value; } }
    Int64 index = 0; public Int64 Index { get { return index; } set { index = value; } }
    String quote = ""; public String Quote { get { return quote; } set { quote = value; } }
    Boolean initialised = false; public Boolean Initialised { get { return initialised; } set { initialised = value; } }
}

public static Names[] _names;
public static void NamesInitialise(Names[] names)
{
    names = new Names[10];
    //
    names[0] = new Names();
    names[0].Name = "LOSANGELES";
    names[0].NameID = 14;
    names[0].Index = 0;
    names[0].Point = Convert.ToDecimal(0.00001);
    names[0].Initialised = true;
    //
    names[1] = new Names();
    names[1].Name = "STOCKHOLM";
    names[1].NameID = 15;
    names[1].Index = 1;
    names[1].Point = Convert.ToDecimal(0.001);
    names[1].Initialised = true;
    //
    names[2] = new Names();
    names[2].Name = "BERLIN";
    names[2].NameID = 21;
    names[2].Index = 2;
    names[2].Point = Convert.ToDecimal(0.00001);
    names[2].Initialised = true;
    //
    names[3] = new Names();
    names[3].Name = "BONN";
    names[3].NameID = 23;
    names[3].Index = 3;
    names[3].Point = Convert.ToDecimal(0.00001);
    names[3].Initialised = true;
    //
    names[4] = new Names();
    names[4].Name = "PARIS";
    names[4].NameID = 24;
    names[4].Index = 4;
    names[4].Point = Convert.ToDecimal(0.00001);
    names[4].Initialised = true;
    //
    names[5] = new Names();
    names[5].Name = "TELAVIV";
    names[5].NameID = 25;
    names[5].Index = 5;
    names[5].Point = Convert.ToDecimal(0.001);
    names[5].Initialised = true;
    //
    names[6] = new Names();
    names[6].Name = "ROME";
    names[6].NameID = 31;
    names[6].Index = 6;
    names[6].Point = Convert.ToDecimal(0.00001);
    names[6].Initialised = true;
    //
    names[7] = new Names();
    names[7].Name = "NEWYORK";
    names[7].NameID = 34;
    names[7].Index = 7;
    names[7].Point = Convert.ToDecimal(0.00001);
    names[7].Initialised = true;
    //
    names[8] = new Names();
    names[8].Name = "LONDON";
    names[8].NameID = 35;
    names[8].Index = 8;
    names[8].Point = Convert.ToDecimal(0.001);
    names[8].Initialised = true;
    //
    names[9] = new Names();
    names[9].Name = "TOKYO";
    names[9].NameID = 45;
    names[9].Index = 9;
    names[9].Point = Convert.ToDecimal(0.001);
    names[9].Initialised = true;
    //
}

public class Base : Names
{
    Decimal basis = 0; public Decimal Basis { get { return basis; } set { basis = value; } }
}
public static Base[] _base;

这就是我在定时上使用它们的方式

protected void Timer1_Tick(object sender, EventArgs e)
{
    Table1.Rows.Clear();
    for (int i = 0; i < 10; i++)
    {
        try
        {
            if (!_yahoo[i].Initialised||!_names[i].Initialised||!_base[i].Initialised)
            {
                NamesInitialise(_yahoo);
                NamesInitialise(_names);
                NamesInitialise(_base);
            }
            else
            {
                Yahoo_Load(_yahoo[i]);
                //
                TableRow _table_row = new TableRow();
                Table1.Rows.Add(_table_row);
                //
                TableCell _cell_1 = new TableCell();
                _cell_1.Text = _names[i].Name;
                _table_row.Cells.Add(_cell_1);
                //
                TableCell _cell_2 = new TableCell();
                _cell_2.Text = Convert.ToString(_base[_names[i].Index].Basis);
                _table_row.Cells.Add(_cell_2);
                //
                TableCell _cell_3 = new TableCell();
                _cell_3.Text = _names[i].Quote;
                _table_row.Cells.Add(_cell_3);
                //
            }
        }
        catch
        {
            //Commented this out on purpose and null exception errors are thrown. 
            //That should not be the case.
            /*
            NamesInitialise(_yahoo);
            NamesInitialise(_names);
            NamesInitialise(_base);
            */
        }
    }
}

public static void NamesInitialise(Names[] names)
{
    names = new Names[10];

public static Names[] NamesInitialise()
{
    var names = new Names[10];
    .....
    return names;
}
