基于特定值将列表拆分为两个

问题描述

我有以下情况：

Hi,
I have the following scenario:

public Class Form
{
public string Name {get; set;}
public string FormID {get; set;}
public string Path {get; set;}
}

List<Form>pdfdoc = new List<Form>{
new Form{ Name="Form1", FormID ="1", Path="D:/Temp/"},
new Form{ Name="Form2", FormID ="2", Path="D:/Temp/"},
new Form{ Name="Form3", FormID ="3", Path="D:/Temp/"},
new Form{ Name="Form4", FormID ="4", Path="D:/Temp/"},
new Form{ Name="Form5", FormID ="5", Path="D:/Temp/"},
new Form{ Name="Form6", FormID ="6", Path="D:/Temp/"},
new Form{ Name="Form7", FormID ="7", Path="D:/Temp/"},
new Form{ Name="Form8", FormID ="8", Path="D:/Temp/"},
};

我希望检查列表是否包含Form4然后将列表拆分为两个列表，第一个列表包含Form1，Form2，Form3，另一个列表包含Form5，Form6，Form7，Form8。有没有办法？

I want that to check if the list contains Form4 and then split the list into two lists, the first list containing Form1,Form2,Form3 and the other containing Form5,Form6,Form7,Form8. Is there any possible way?

推荐答案

var index = pdfdoc.IndexOf(pdfdoc.Find(f => f.Name.Equals("Form")));

if (index > 0)
{
    var list1 = pdfdoc.GetRange(0, index);
    var list2 = pdfdoc.GetRange(index + 1, pdfdoc.Count - index - 1);
}

List<Form> List1 = (from docs in pdfdoc where (docs.FormID.CompareTo("4") < 0) select docs).ToList();

List<Form> List2= (from docs in pdfdoc where (docs.FormID.CompareTo("4") > 0) select docs).ToList();
