使用带分隔符的字符串将项目添加到列表框 [英] Adding items to a Listbox from a string with delimiters

问题描述

如何像使用，"作为分隔符的字符串那样将项目添加到ListBox.就像假设我要向ListBox添加名字.如何从"rupa，anitha，latha，rani"之类的字符串中添加这些项目?

有人可以帮我吗?

在此先感谢！

解决方案

ListBox lst = new ListBox();
        lst.Items.Add(new ListItem("rupa"));
        lst.Items.Add(new ListItem("anitha"));
        lst.Items.Add(new ListItem("latha"));
        lst.Items.Add(new ListItem("rani"));

那就是你要找的东西吗?

好了，正如曼弗雷德(Manfred)所建议的那样，我可以像
那样修改答案

string str = "hiren,manfred,you,me,all,cp";
string[] items = str.split('','');

for(int i=0;i<items.length;i++)>
{
lst.add(new ListItem(string[i]));
}

尝试一下:

  public  ListBox AddItemsToListBoxFromString(ListBox lb， String  strItems，字符 []分隔符)
{
    字符串 [] items = strItems.Split(separators);
     foreach (字符串项目 in 项目中)
    {
        lb.Items.Add(item.Trim());
    }
    返回 lb；
} 

来自文件背后代码的典型调用可能如下所示:

 ...
AddItemsToListBoxFromString(listBox1，" ，字符 [] { ，'});
...

希望对您有帮助！

最好的问候，
曼弗雷德(Manfred)

形式上，已经有正确的答案.

我会建议对所有显示的代码进行小幅改进:

 字符串 []项目= source.Split(
    新 字符 [] {' '，' ，'}，
    StringSplitOptions.RemoveEmptyEntries); 

How can I add items to ListBox like from a string using "," as a delimiter. Like suppose I want to add first names to a ListBox. How can I add these items from a string like "rupa,anitha,latha,rani"?

Can any body help me?

Thanks in advance!

解决方案

ListBox lst = new ListBox();
        lst.Items.Add(new ListItem("rupa"));
        lst.Items.Add(new ListItem("anitha"));
        lst.Items.Add(new ListItem("latha"));
        lst.Items.Add(new ListItem("rani"));

That is what you looking for ?

Ok now as manfred suggested I can revise my answer like

string str = "hiren,manfred,you,me,all,cp";
string[] items = str.split('','');

for(int i=0;i<items.length;i++)>
{
lst.add(new ListItem(string[i]));
}

Try this:

public ListBox AddItemsToListBoxFromString(ListBox lb, String strItems, char[] separators)
{
    String[] items = strItems.Split(separators);
    foreach(String item in items)
    {
        lb.Items.Add(item.Trim());
    }
    return lb;
}

A typical call from a code behind file might look like this:

...
AddItemsToListBoxFromString(listBox1, "rupa,anitha,latha,rani", new char[] { ',' });
...

Hope this helps you!

Best Regards,
Manfred

Formally, there are correct answers already.

I would add advice a minor improvement to all the presented codes:

string[] items = source.Split(
    new char[] { ' ', ',' },
    StringSplitOptions.RemoveEmptyEntries);

It allows for more relaxed human-readable requirements for the format of the input.
