我想使用 c# 读取 php 文本文件。该文件如下所示:
2.20:2.20:2.20:2.20:2.20:
2012-07-12:2012-07-11:2012-07-10:2012-07-09:2012-07-08:
我想将所有行都添加到列表框。在实际情况中有六行,但首先我应该阅读这两行。我的代码:
void web_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
try
{
int i;
string price_line = "";
string date_line = "";
List<decimal> prices = new List<decimal>();
List<string> dates = new List<string>();
using (var reader = new StreamReader(e.Result))
{
price_line = reader.ReadLine();
date_line = reader.ReadLine();
string[] bit_1 = price_line.Split(':');
string[] bit_2 = date_line.Split(':');
for (i = 0; i < 2; i++)
{
prices.Add(decimal.Parse(bit_1[i]));
dates.Add(bit_2[i]);
}
listBox1.ItemsSource = prices;
listBox2.ItemsSource = dates;
}
}
catch
{
MessageBox.Show("Can't read!");
}
}
现在我得到“NullException”。如何解决这个问题?
