c#怎样定义全局数组

Question

c#怎样定义全局数据，定义了一个全局数组，给分配数据时提示“”未将对象引用设置到对象的实例。“”
public static string[] TelList;
private void OpenMenu_Click(object sender, EventArgs e)
{
for (int j = 0; j < tel_list_lines; j++)
{
effective++;
TelList[j] = tel_list[j];
}
}

Answer 1

public static string[] TelList;

这个只是声明，还没初始化。
private void OpenMenu_Click(object sender, EventArgs e)
{
TelList = new string[tel_list_lines];//这里要初始化数组，不然就会报未将对象的错
for (int j = 0; j < tel_list_lines; j++)
{
effective++;
TelList[j] = tel_list[j];
}
}
