本节把form主线程从其他线程分离出来，实现数据从线程的传入传出
代码如下：
from1.cs代码如下：
using system;
using system.drawing;
using system.collections;
using system.componentmodel;
using system.windows.forms;
using system.data;
using system.threading;
namespace student

public class form1 : system.windows.forms.form
{

private system.windows.forms.button button2;
private system.windows.forms.button button3;
private class1 c;
private system.windows.forms.listview listview1;
private system.windows.forms.columnheader columnheader1;
private system.windows.forms.columnheader columnheader2;
/// <summary>

}

}
}
base.dispose( disposing );
}

}
}
