输出文本文件
问题描述：
我正在将信息写入文件，并将其命名为"//Average+DateTime.txt";我想我的代码会更容易比我想澄清：输出文本文件
String path=bama();
if(path.Contains(".txt")) {
StreamWriter sw=
new StreamWriter(
"C:/Users/msilliman11/Average"
+DateTime.Now.ToString("yyyyMMdd")
+".txt"
);
}
String ElementsNum=RoundedValues.Count.ToString();
DateTime dt=System.DateTime.Now;
using(var NewFile=File.Create(path)) {
using(var writeIt=new StreamWriter(NewFile)) {
writeIt.Write(
"NA"+","
+dt.Hour.ToString()+","+dt.Minute+","
+dt.Day+","+dt.Month.ToString()+","+dt.Year.ToString()+","
+"ALTEST "+","+"ALTEST "+","+heatgrade
+" "+","+" "+","+heatname+","
+DT2.Columns[3].ToString()+","+heatgrade+","
+"OE2"+","+","+","+","+","+","+","+" "+ElementsNum+","
);
foreach(
var pair in
RoundedValues.Zip(
Elements, (a, b) => new {
A=a,
B=b
})) {
writeIt.Write(pair.B.ToString()+","+pair.A.ToString()+",");
}
}
}
我的问题是，我需要命名"Average"文件，并在写入文件外使用的代码块...
我敢坏在解释这些问题，但基本上即时通讯试图让第二块使用的信息，被命名为输出文件中"4222013Average.txt" ...

如果我正确地理解你的问题，我认为这可能更好地为你。
var toFile = Path.Combine(@"C:\Users\msilliman11\",
string.Format("Average{0}.txt", DateTime.Now.ToString("yyyyMMdd")));
var dt = DateTime.Now;
using (var fs = File.OpenWrite(toFile))
using (TextWriter sw = new StreamWriter(fs))
{
sw.Write(string.Join(",",
"NA",
dt.Hour,
dt.Minute,
dt.Day,
dt.Month,
dt.Year,
"ALTEST ",
"ALTEST ",
heatgrade,
" ",
" ",
heatname,
DT2.Columns[3],
heatgrade,
"OE2",
string.Empty,
string.Empty,
string.Empty,
string.Empty,
string.Empty,
string.Empty,
string.Empty,
" ",
","));
foreach (var pair in RoundedValues.Zip(Elements, (a, b) => new { A = a, B = b }))
{
writeIt.Write(pair.B.ToString() + "," + pair.A.ToString() + ",");
}
}

这并不完全清楚是什么问题是，除了：
你说你想命名文件：4/22/2013Average.txt。这不可能。文件名中不允许使用正斜杠。
这是你需要知道的吗？如果没有，请更清楚。
另外一个提示：请使用string.Format()你的代码更易读：
string text = string.Format("NA,{0},{1},{2},{3},{4},ALTEST,ALTEST ,{5} , ,{6},{7},{5},OE2,,,,,,, {8},",
dt.Hour,
dt.Minute,
dt.Day,
dt.Month,
dt.Year,
heatgrade,
heatname,
DT2.Columns[3],
ElementsNum);
writeIt.Write(text);
您在第一“命名它作为//Average+DateTime.txt说：”然后你提到的“命名‘4月22日/ 2013Average.txt’，所以它的格式是你想要的吗？ – 2013-04-23 01:18:10
对不起，最后一个是正确的，我把斜线放在那里也犯了一个错误， – 2013-04-24 20:51:44
