Question

I try to create multiple objects based of one blueprint class and want to fill them with values from an array.

My Blueprint would look as follows:

public class Participant
{
    string DateOfBirth;
    string Gender;
    double BmiValue;
    double RelativeFatMass;
    double AbsoluteFatMass;
    double FatFreeMassValue;
    double SkeletalMuscleMassValue;
    double SmmTorsoValue;
    double SmmRlValue;
    double SmmLlValue;
    double SmmLaValue;
    double SmmRaValue;
    double WaistCircumferenceValue;
    double WeightValue;
    double HeightValue;
    double TotalEnergyExpenditureValue;
    double RestingEnergyExpenditureValue;
    double FfmiValue;
    double FmiValue;
    double VisceralAdiposeTissueValue;
}

I aim to create objects and fill all those fields with the set values from my array. After on Object is done, I want the same function to create the next object and to repeat this depending on the length of the array.

您用蓝图描述的内容实际上是一个名为inheritance的概念。我建议你在潜水之前先阅读一下，但这里有一个例子，包括你想要做的事情：

<强> Participant.cs

public class Participant
{
    public string firstName { get; set; }
    public string secondName { get; set; }
    public string gender { get; set; }

    public Participant(string firstName, string secondName, string gender)
    {
        this.firstName = firstName;
        this.secondName = secondName;
        this.gender = gender; 
    }

    public Participant(string[] args)
    {
        this.firstName = args[0];
        this.secondName = args[1];
        this.gender = args[2];
    }
}

ParticipantExtended.cs （注意：您可以将其命名为比这更好的东西！）

public class ParticipantExtended : Participant
{
    public ParticipantExtended(string firstName, string secondName, string gender) : base(firstName, secondName, gender)
    {
        this.firstName = firstName;
        this.secondName = secondName;
        this.gender = gender; 
    }

    public ParticipantExtended(string[] args) : base(args)
    {
        this.firstName = args[0];
        this.secondName = args[1];
        this.gender = args[2]; 
    }
}

我们必须再次创建构造函数，因为每个类必须定义自己的构造函数。我放下2个构造函数的原因仅仅是出于示例目的。

SomeFunction（）这是您拥有值并想要创建对象的时候

        // Supplying parameters to constructor 
        ParticipantExtended person1 = new ParticipantExtended("John", "Smith", "Male");
        // Supplying an array to the constructor 
        string[] informationAboutPerson = { "Jane", "Jones", "Female" };
        ParticipantExtended person2 = new ParticipantExtended(informationAboutPerson);

        // Results 
        string name = person1.firstName; // name = John 
        string gender = person2.gender; // gender = female

虽然有些不相关，但我建议你看看interfaces，因为在C＃中你不能从超过1个类继承。

C# using class as blueprint for multiple objects
