在现有的stringcollection中添加另一个字符串 [英] adding another string to existing stringcollection

问题描述

你好



我有这个代码用于通过displayindex，width和visibility创建我的datagridview的stringCollection dg，它工作得很好，我将它保存到Properties。设置，但我需要添加另一个字符串或更好说我需要添加第5个字符串，这将是我创建的每个stringCollection的模板的ID，（我有多个用户）



基本上我的xml文件看起来像这样

Hello

I have this code for creating stringCollection of my datagridview called dg by displayindex, width and visibility and it's working great,I am saving it to Properties.Settings , but I need to add another string or better said I need to add 5th string, which will be ID of template of each stringCollection I am creating, (I have multiple users)

basically I my xml file look like this

00,100,False,0
01,100,False,1
.....

我想加5号

and I want to add 5th

00,100,False,0,1
01,100,False,1,1
....

00,100,False,0,2
01,100,False,1,2
....

所以当我用第5个字符串调用stringCollection时，我只得到第5个字符串的stringCollection

so when I call stringCollection by that 5th string I get only stringCollection with that string in 5th

StringCollection stringCollection = new StringCollection();
int i = 0;
foreach (DataGridViewColumn column in this.dg.Columns)
{
    stringCollection.Add(string.Format(
        "{0},{1},{2},{3}",
        column.DisplayIndex.ToString("D2"),
        column.Width,
        column.Visible,
        i++));
}
Settings.Default.columns = StringCollection;
Settings.Default.Save();

推荐答案

也许你的string.Format需要更新。



类似于：

Maybe your string.Format needs to be updated.

Something like:

stringCollection.Add(string.Format(
    "{0},{1},{2},{3}, {4}",
    column.DisplayIndex.ToString("D2"),
    column.Width,
    column.Visible,
    i++,
    ID)
);

我不知道，因为我几乎不明白你的问题。

I don't know because I barely understood your question.
