Question

我需要帮助来找出可用于向Windows窗体添加自定义标签数量的代码。我正在使用默认的Windows窗体应用程序项目进行测试。我找出代码的方法可能有用，如果我使用一个对象数组并在特定的地方添加循环来迭代每个声明。

这是我到目前为止所做的，我不确定如何让程序识别smartLabel数组，请帮忙。

自己想出来。

#pragma once
namespace gui {

    using namespace System;
    using namespace System::ComponentModel;
    using namespace System::Collections;
    using namespace System::Windows::Forms;
    using namespace System::Data;
    using namespace System::Drawing;

    public ref class Form1 : public System::Windows::Forms::Form{
        public:
        Form1(void){
            InitializeComponent();
            BuildLabels();
        }

        private:array<System::Windows::Forms::Label^>^ labels; 

#pragma region Windows Form Designer generated code
    void InitializeComponent(void){
        this->SuspendLayout();
        this->AutoScaleDimensions = System::Drawing::SizeF(6, 13);
        this->AutoScaleMode = System::Windows::Forms::AutoScaleMode::Font;
        this->ClientSize = System::Drawing::Size(200, 220);
        this->Name = L"Form1";
        this->Text = L"Form1";
        this->ResumeLayout(false);
    }
    void BuildLabels(){
        array<String^>^ smartLabel = gcnew array<String^> {L"label1",L"label2",L"label3",L"label4", L"label5",L"label6",L"label7",L"label8",L"label9",L"label10"};
        labels = gcnew array<System::Windows::Forms::Label^>(10);
        for (int i = 0; i < labels->Length; i++)
        {
            labels[i] = gcnew Label();
            labels[i]->AutoSize = true;
            labels[i]->Location = System::Drawing::Point(10, 20*i+10);
            labels[i]->Name = smartLabel[i];
            labels[i]->Size = System::Drawing::Size(50, 15);
            labels[i]->TabIndex = 0;
            labels[i]->Text = smartLabel[i]; 
        }
        Controls->AddRange(labels);
    }
#pragma endregion
    };
}
