我已将JSON粘贴到我的C#控制台应用程序中,因此它会生成如下类:
public class Rootobject
{
public Id id { get; set; }
}
public class Id
{
public Identifier Identifier { get; set; }
}
public class Identifier
{
public Id1 id { get; set; }
public Type type { get; set; }
}
public class Id1
{
public string IdentifierString { get; set; }
}
public class Type
{
public string IdentifierType { get; set; }
}
我希望设置identifierString
和identifierType
的值,如下所示:
var node = new Rootobject();
node.id.Identifier.id.IdentifierString = "testId";
node.id.Identifier.type.IdentifierType = "idType";
但是,我得到的对象引用未设置为对象的实例'错误。

你应该写:
var node = new Rootobject();
node.id = new Id();
node.id.Identifier = new Identifier();
node.id.Identifier.id = new Id1();
node.id.Identifier.type = new Type();
node.id.Identifier.id.IdentifierString = "testId";
node.id.Identifier.type.IdentifierType = "idType";
甚至更好:
var node = new Rootobject
{
id = new Id
{
Identifier = new Identifier
{
id = new Id1 { IdentifierString = "id" },
type = new Type { IdentifierType = "type" },
}
}
};
您缺少对象的创建,它们是空的

或编译的版本:)
var node = new RootObject
{
id = new Id
{
Identifier = new Identifier
{
id = new Id1 { IdentifierString = "id" },
type = new Type { IdentifierType = "type" },
}
}
};
