如何动态地分割字符串 [英] how to split string in dynamicaly

问题描述

Hai Friends，

我想在文本框中显示数据，如
id:111
名称:venkat
颜色:绿色
因此，在此之前，我仅显示诸如
之类的数据 111
venkat

.................
现在我要这样显示

这是我的代码

            string[] strListItems;
            int intNumItems = comboBox1.Items.Count;
            strListItems = new string[intNumItems];
            for (int i = 0; i < comboBox1.Items.Count; i++)
            {
                strListItems[i] = ds.Tables[0].Rows[comboBox1.SelectedIndex][i].ToString();
                str2 = str2 + "\r\n " +strListItems[i];
            }
            textBox1.Text = str2;

请给我任何想法.


谢谢

推荐答案

更改代码，如

Change your code like

string str2 = "";
string[] strListItems = { "id", "name", "color" };
for (int i = 0; i < comboBox1.Items.Count; i++)
{
    str2 +=  strListItems[i] + ":" + ds.Tables[0].Rows[comboBox1.SelectedIndex][i].ToString() + "\r\n ";
}
textBox1.Text = str2;

那是什么问题?什么对您不起作用?在我看来，您需要添加代码以插入列名，这对我来说似乎是一项微不足道的任务.您可以将它们存储在数组中，以便也按索引读取它们，或者可以编写不使用循环的代码来对列名称进行硬编码.无论哪种方式，对我来说似乎都是一种差劲的方法，但这行得通.

So what is the problem ? What is not working for you ? It looks to me like you need to add code to insert your column names, which seems like a trivial task to me. You could store them in an array so you read them by index, too, or you could write code that does not use a loop, to hard code the column names. Either way, it seems like a poor approach to me, but that would work.
