c# - 从代码中声明多个字符串

Question

我有这样的东西:

XmlDocument doc = new XmlDocument();
doc.Load(@"D:\filter.xml");
string filter1 = doc.SelectSingleNode("filter/f1").InnerText;
string filter2 = doc.SelectSingleNode("filter/f2").InnerText;
string filter3 = doc.SelectSingleNode("filter/f3").InnerText;
string filter4 = doc.SelectSingleNode("filter/f4").InnerText;
string filter5 = doc.SelectSingleNode("filter/f5").InnerText;
string filter6 = doc.SelectSingleNode("filter/f6").InnerText;

等等...我的问题是如何在循环中生成这些字符串？类似的东西。

XmlDocument doc = new XmlDocument();
doc.Load(@"D:\filter.xml");
for (int i = 0; i < 7; i++)
{
    string filter + i = doc.SelectSingleNode("filter/f" + i).InnerText;;        
}

Answer 1

填写List<string> :

List<string> filterList = new List<string>();
for (int i = 0; i < 7; i++)
{
    filterList.Add(doc.SelectSingleNode("filter/f" + i).InnerText);
}

现在您可以通过索引访问它们，f.e.过滤器 5:

string filter5 = filterList[4]; // zero based
