c#多线程委托返回值问题

C#多线程操作ui组件的时候怎样调用返回值
private delegate void ThreadWork2(int i,string result,string sendtime);
private void SendMenu_Click(object sender, EventArgs e)
{
Thread thread = new Thread(new ThreadStart(GetValue));
thread.Start();
}
void GetValue(){
for (int i = 0; i < list.Items.Count; i++)
{
TelListFlagFunction(i,result,sendtime);
Thread.Sleep(500);
}
}
private void TelListFlagFunction(int i, string result, string sendtime)
{
if (this.list.InvokeRequired)
{
ThreadWork2 fc = new ThreadWork2(TelListFlagFunction);
this.Invoke(fc,new object[]{i,result,sendtime});
}
else {
this.list.Items[i].SubItems[1].Text = result;
this.list.Sorting = System.Windows.Forms.SortOrder.None;
this.list.Items[i].SubItems.Add(sendtime);
}
}
Tellistflagfunction怎样根据getvalue里面的变量给GetValue返回个字符串，

Answer 1

private delegate stringThreadWork2(int i,string result,string sendtime); //把void 换成 string 返回string字符串

Answer 2

你说的getvalue在哪？C#是大小写敏感的

追问

void GetValue(){
for (int i = 0; i < list.Items.Count; i++)
{
TelListFlagFunction(i,result,sendtime);
Thread.Sleep(500);
}
}

怎样根据getvalue里面的变量给GetValue返回个字符串---为什么你一个小写一个大写
