谷歌API：让空上阵

Question

System.NullReferenceException：对象不设置到对象的实例

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(); 

我得到空值newuserorg [0] .CostCenter

我使用Google Admin API和C＃更新用户的组织详细信息。 谢谢。

UPDATE：现在有效，我只是忘了实例化。谢谢。

Answer 1

您的阵列有10个空插槽。你需要填充新的对象。

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

Answer 2

您是否试图将值分配给UserOrganization实例？

然后尝试：

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

Answer 3

这里是你想什么（也许）一个完整的构造做：

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; } 
}
