Google API:在数组上获取Null

Question

System.NullReferenceException：对象引用未设置为对象的实例

UserOrganization[] newuserorg = new UserOrganization[10];
newuserorg[0].CostCenter = "test";
newuserorg[1].Department = "test";
newuserorg[2].Description = "test";
newuserorg[3].Domain = "demo.com";
newuserorg[4].Symbol = "TWW";
newuserorg[5].Primary = true;
newuserorg[6].Title = "title";
newuserorg[7].Type = "work";
newuserorg[8].Name = "HEY";
newuserorg[9].Location = "PH";
newuserbody.Organizations = newuserorg;
service.Users.Update(newuserbody, email).Execute();

我得到newuserorg[0]的空值。CostCenter

我正在使用Google Admin API和C#来更新用户的组织详细信息。谢谢

UPDATE：现在可以工作了，我只是忘了实例化。谢谢

Answer 1

您的数组有10个空槽。您需要用新对象填充它们。

            for (int i = 0; i < newuserorg.Length; i++)
            newuserorg[i] = new UserOrganization();

Answer 2

是否尝试为UserOrganization实例赋值？

然后尝试：

UserOrganization newuserorg = new UserOrganization();
newuserorg.setCostCenter = "test";
newuserorg.setDepartment = "test";
...
...

以下是您尝试(可能(要做的事情的完整构造函数：

public class Program
{
    public void Main(string[] args)
    {
        UserOrganization[] newuserorg = new UserOrganization[10];
        newuserorg[0] = new UserOrganization("test", "test", "test", "demo.com", "test", true, "test", "test", "test", "test");
    }
}
public class UserOrganization
{
    public UserOrganization()
    {
    }
    public UserOrganization(string costCenter, string department, string description, string domain, string symbol, bool primary, string title ,string type , string name, string location)
    {
        CostCenter = costCenter;
        Department = department;
        Description = description;
        Domain = domain;
        Symbol = symbol;
        Primary = primary;
        Title = title;
        Type = type;
        Name = name;
        Location = location;
    }
    public string Name { get; set; }
    public string CostCenter { get; internal set; }
    public string Department { get; internal set; }
    public string Description { get; internal set; }
    public string Domain { get; internal set; }
    public string Symbol { get; internal set; }
    public bool Primary { get; internal set; }
    public string Title { get; internal set; }
    public string Type { get; internal set; }
    public string Location { get; internal set; }
}
