Sending a string to a listbox (C#)
提问by Mathew
I currently have a string being sent to a TextBox, although instead is it possible to send it to a listbox?
我目前有一个字符串被发送到文本框，但是否可以将它发送到列表框？
private void buttonLB_Click(object sender, EventArgs e)
{
string machineName = (@"\" + System.Environment.MachineName);
ScheduledTasks st = new ScheduledTasks(machineName);
// Get an array of all the task names
string[] taskNames = st.GetTaskNames();
richTextBox6.Text = string.Join(Environment.NewLine, taskNames);
st.Dispose();
}
回答by David Ruttka
You can add the joined task names as a single item
您可以将加入的任务名称添加为单个项目
listbox1.Items.Add(string.Join(Environment.NewLine, taskNames));
Or you can add each of the task names as a separate item
或者您可以将每个任务名称添加为单独的项目
foreach (var taskName in taskNames)
{
listbox1.Items.Add(taskName);
}

Instead of setting the textbox's Textproperty, add a ListItemto the listbox's Items collection.
不要设置文本框的Text属性，而是将 a 添加ListItem到列表框的 Items 集合。
lstBox.Items.Add(new ListItem(string.Join(Environment.NewLine, taskNames));
Or...
或者...
foreach(var taskName in taskNames)
lstBox.Items.Add(new ListItem(taskName));

Use AddRange, this can take an array of objects.
使用 AddRange，这可以接受一个对象数组。
Here's some sample code:
这是一些示例代码：
Start a new WinForms project, drop a listbox on to a form:
启动一个新的 WinForms 项目，将列表框拖放到表单上：
string[] names = new string[3];
names[0] = "Item 1";
names[1] = "Item 2";
names[2] = "Item 3";
this.listBox1.Items.AddRange(names);
For your specific example:
对于您的具体示例：
// Get an array of all the task names
string[] taskNames = st.GetTaskNames();
this.listBox1.Items.AddRange(taskNames);
If this is called repeatedly, call clear as needed before adding the items:
如果重复调用，请在添加项目之前根据需要调用 clear：
this.listBox1.Items.Clear();
