如何通过索引从列表框中获取文本？

Question

I am trying to get text from an entry in my winForms ListBox by index, but I seem to be stumped. The only logical thing I can think of is:

listBox.Items[index].ToString

But this does not return the desired result.

Does anyone know how to do this?

Answer 1

What do you have in your Listbox?

If there are string values in the listbox, your code is correct except for missing braces:

string value = listBox.Items[index].ToString();

If the things in the listbox are some sort of object, you may need to override ToString() to get the desired result, or cast the thing you get out of the listbox to the desired type and then access an appropriate property.

Example:

MyClass my = (MyClass)listBox.Items[index];
string value = my.SomePropertyOfMyClass;

Answer 2

使用此listBox.Items[index].Text

Answer 3

要通过索引从ListBox的项目中获取项目，请使用此方法

string item = listBox1.Items[0];
