例如:
List<Projects> projectList = new List<Projects>
{
new Project
{
id = 100500,
Subprojects = new List<Subproject>
{
new Subproject { Project = "**Need to pass pointer on the project**" },
}
}
}
如何传递这个指针?
这是一个关于语法的问题,我清楚地知道可以用另一种方式做到这一点。

如何只为每个类添加标准函数/构造函数?
例如:
List<Project> cProjects = new List<Project> { new Project(100500) };
public class Project
{
public Project(int id)
{
this.id = id;
Subprojects = new List<Subproject> { new Subproject(this) };
}
public int id;
public List<Subproject> Subprojects;
}
public class Subproject
{
public Subproject(Project project)
{
this.Project = project;
}
public Project Project;
}

您无法在单个语句中执行此操作:您希望分配给Project
的指针(实际上,引用)在您要分配它时未分配。您需要使用中间变量 - 例如,像这样:
Project p;
List<Projects> projectList = new List() {
p = new Project() {
id = 100500
, Subprojects = new List<Subproject>()
}
};
p.Subprojects.Add(
new Subproject { Project = p }
);
