问题描述:
public class a:Form
{
public DateTime startdate;
pubiic DateTime enddate;
public a
{
}
private void Button1_Click(object sender,EventArgs e)
{
b f1=new b();
f1.type=typeof(a);
f1.Owner=this;
f1.Show();
}
}
public class b:Form
{
Public Type type;
Public b()
{
}
private void Button1_click(object sender,EventArgs e)
{
((type)this.Owner).startdate=...;//出错的地方
((type)this.Owner).enddate=....;//出错的地方
}
}
运行时会出现错误:b.type表示字段,此处就为类
各位老大,请问如何解决!!
private void Button1_click(object sender,EventArgs e)
{
((type)this.Owner).startdate=...;//出错的地方
((type)this.Owner).enddate=....;//出错的地方
}
==============================>
private void Button1_click(object sender,EventArgs e)
{
object oa = this.Owner;
a aform;
if( aform as a != null )
{
aform .startdate=...;//出错的地方
aform .enddate=....;//出错的地方
}
up
sorry ,写错了
private void Button1_click(object sender,EventArgs e)
{
a aform = this.Owner as a
if( aform != null )
{
aform .startdate=...;//出错的地方
aform .enddate=....;//出错的地方
}
}
((Type)this.Owner).startdate=...;//出错的地方
是要反射吧
using System.Reflection;
...
//出错的地方
FieldInfo myFieldInfo1 = type1.GetField("startdate", BindingFlags.Public | BindingFlags.Instance);
myFieldInfo1.SetValue(this.Owner,"起始日期");
