我有两个列表保存到一个名为 ListType 的类中,如下所示。我正在尝试在匹配类类型值时将两个列表相互匹配。两个列表都包含县和 act_loc 类类型,所以我要做的是 fileList 列表中的县和 act_loc 等于人口普查文件中的县和 act_loc,如果是这样,我想将所有类类型数据写入文件列表列表。
ListType 类:
public class ListType
{
public ListType()
{
}
public string ID { get; set; }
public string REGSID { get; set; }
public string county { get; set; }
public string act_loc { get; set; }
public string hmonth { get; set; }
public string hisnc { get; set; }
public string hinc { get; set; }
public string black00 {get; set;}
public string asian00 { get; set; }
public string hispanic00 { get; set; }
public string pop2000 { get; set; }
public string popden2000 { get; set; }
public string totalunder18_00 { get; set; }
public string sixtyfiveplus_00 { get; set; }
public string percentforeign_00 { get; set; }
public string percentsixteenplusinmanu_00 { get; set; }
public string medhouseholdinc_00 { get; set; }
public string totalbelowPOV_00 { get; set; }
public string englishverywell_00 { get; set; }
public string black10 { get; set; }
public string asian10 { get; set; }
public string hispanic10 { get; set; }
public string pop2010 { get; set; }
public string popden2010 { get; set; }
public string totalunder18_10 { get; set; }
public string sixtyfiveplus_10 { get; set; }
public string percentforeign_10 { get; set; }
public string percentsixteenplus_10 { get; set; }
public string medhouseholdinc_10 { get; set; }
public string totalbelowPOV_10 { get; set; }
public string englishverywell_10 { get; set; }
public string etype { get; set; }
public string etypeText { get; set; }
public string edate { get; set; }
public string fmp_amt { get; set; }
public string newenftype_text { get; set; }
public string finalenftype_text { get; set; }
}
}
一个文件解析为列表:
public static List<ListType> census = new List<Listtype>();
using (StreamReader read = new StreamReader(Filename))
{
read.ReadLine();
while (!read.EndOfStream)
{
string line = read.ReadLine();
string[] splitline = line.Split(',');
ListType l = new ListType();
l.county = splitline[0].ToString();
l.act_loc = splitline[1].ToString();
l.black00 = splitline[2].ToString();
l.asian00 = splitline[3].ToString();
l.hispanic00 = splitline[4].ToString();
l.pop2000 = splitline[5].ToString();
l.popden2000 = splitline[6].ToString();
l.totalunder18_00 = splitline[7].ToString();
l.sixtyfiveplus_00 = splitline[8].ToString();
l.percentforeign_00 = splitline[9].ToString();
l.percentsixteenplusinmanu_00 = splitline[10].ToString();
l.medhouseholdinc_00 = splitline[11].ToString();
l.totalbelowPOV_00 = splitline[12].ToString();
l.englishverywell_00 = splitline[13].ToString();
l.hispanic10 = splitline[14].ToString();
l.black00 = splitline[15].ToString();
l.asian00 = splitline[16].ToString();
l.sixtyfiveplus_10 = splitline[17].ToString();
l.totalunder18_10 = splitline[18].ToString();
l.englishverywell_10 = splitline[19].ToString();
l.percentforeign_10 = splitline[20].ToString();
l.percentsixteenplus_10 = splitline[21].ToString();
l.medhouseholdinc_10 = splitline[22].ToString();
l.totalbelowPOV_10 = splitline[23].ToString();
l.pop2010 = splitline[24].ToString();
l.popden2010 = splitline[25].ToString();
census.Add(l);
}
}
解析为 FileList 列表的其他文件:
public static List,ListType> FileList = new List<ListType>();
using (StreamReader read = new StreamReader(Filename))
{
read.ReadLine();
while (!read.EndOfStream)
{
a++;
string line = read.ReadLine();
string[] splitline = line.Split(',');
ListType l = new ListType();
l.ID = splitline[0].ToString();
l.REGSID = splitline[1].ToString();
l.act_loc = l.ID.Substring(0, 2);
l.county = splitline[2].ToString();
l.hmonth = splitline[4].ToString();
l.hisnc = splitline[5].ToString();
l.hinc = splitline[6].ToString();
l.etype = splitline[7].ToString();
l.etypeText = splitline[8].ToString();
l.edate = splitline[9].ToString();
l.fmp_amt = splitline[10].ToString();
l.finalenftype_text = splitline[11].ToString();
fileList.Add(l);
}
}
Foreach ListType 县和 FileList 中的 act_loc 我想查看人口普查列表中是否存在同一个县和 act_loc(同一县和 act_loc 可能在 FileList 列表中存在多次,它只会在人口普查列表中出现一次),如果是的话我想将人口普查列表中的所有数据写入 FileList List。做这部分有困难。我想遍历 FileList 中的每条记录,如果它存在于人口普查列表中,我想将人口普查数据写入 FileList 记录,但是在下面的人口普查中,当我写入数据时不存在我如何访问人口普查行,以便我可以将其写入 fileList 列表。
foreach (ListType l in fileList)
{
bool exists = census.Exists(p => p.county == l.county && p.act_loc == l.act_loc);
if (exists)
{
//census data record to matching FileList record
l.black00 = census.black00;
l.asian00 = census.asian00;
l.hispanic00 = census.hispanic00;
l.pop2000 = census.pop2000;
l.popden2000 = census.popden2000;
l.totalunder18_00 = census.totalunder18_00;
l.sixtyfiveplus_00 = census.sixtyfiveplus_00;
l.percentforeign_00 = census.percentforeign_00;
l.percentsixteenplusinmanu_00 = census.percentsixteenplusinmanu_00;
l.medhouseholdinc_00 = census.medhouseholdinc_00;
l.totalbelowPOV_00 = census.totalbelowPOV_00;
l.englishverywell_00 = census.englishverywell;
l.hispanic10 = census.hispanic10;
l.black00 = census.black10;
l.asian00 = census.asian10;
l.sixtyfiveplus_10 = census.sixtyfiveplus_10;
l.totalunder18_10 = census.totalunder18_10;
l.englishverywell_10 = census.englishverywell_10;
l.percentforeign_10 = census.percentforeign_10;
l.percentsixteenplus_10 = census.percentsixteenplus_10;
l.medhouseholdinc_10 = census.medhouseholdinc_10;
l.totalbelowPOV_10 = census.totalbelowPOV_10;
l.pop2010 = census.pop2010;
l.popden2010 = census.popden2010;
}
}
