Question

我意识到这已被部分涵盖，但我相信我所遇到的问题尚未完全涵盖：

我有一个事件在事件发生时创建Form的对象：

    private void hostView_AfterSelect(object sender, TreeViewEventArgs e)
    {
        string selectedNodeText = e.Node.Text;
        if (selectedNodeText == "Internal Hosts" || selectedNodeText == "External Hosts")
        {
            // ignore, parent nodes have no corrosponding tab!
        }
        else
        {
            Form1 Form1Object = new Form1(selectedNodeText);
            Form1Object.Show();
        }

    }

虽然我需要创建Form1的许多对象，具体取决于"selectedNodeText"字符串值。

例如：如果"selectedNodeText"为== "Cars"，我希望将Form1的对象名称称为"Form1ObjectCars"，如果它是"Dogs"对象名称为"Form1ObjectDogs"。

Answer 1

您可以使用Dictionary<TKey,TValue>类，例如

//Initialize
Dictionary<string, Form1> forms = new Dictionary<string, Form1>();

//Add objects 
if(selectedNodeText == "foo")
    forms.Add("foo", new Form1("foo"));

if(selectedNodeText == "bar")
    forms.Add("bar", new Form1("bar"));

//Get objects 
Form1 bar = forms["bar"];

Answer 2

听起来你正在使用相同的表单，但只想标题或标题不同。

string caption = string.Format("Form1Object{0}", selectedNodeText);
Form1 Form1Object = new Form1(caption); 
// in the Form's constructor you are doing a this.Text = caption?
Form1Object.Show();

或者为了避免将其传递给表单：

Form1 Form1Object = new Form1(); 
Form1Object.Text = string.Format("Form1Object{0}", selectedNodeText);
Form1Object.Show();

如何动态创建表单的对象名称
