Question

我有一小段代码：

public DisabledStudent(int id, int age, bool requiressupport)
{
this.requiressupport = requiressupport;
}

该数组类似于以下内容：

public partial class Form1 : Form
{
const int MaxStudents = 4;

public Form1()
{
    InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
 Student[] studentList;
 studentList = new Student[4];

 studentList[0] = new Student(51584, 17);
 studentList[1] = new Student(51585, 19);
 studentList[2] = new Student(51586, 15);
 studentList[3] = new Student(51587, 20);

    for (int i = 0; i < MaxStudents; i++)
    {
         lstStudents.Items.AddRange(studentList);
    }
}

我想要做的是从学生数组输出一个字符串，基本上显示文本的不同部分，具体取决于requiressupport布尔值是true还是false：

public override string ToString()
{
    return string.Format("Disabled Student - ID: {0} (Age {1})", this.Number, this.Age);
}

如果Disabled Student - ID: 45132 (Age 19) with support布尔为requiressupport，我希望上面的语句基本上说true如果Disabled Student - ID: 45132 (Age 19) without support布尔是requiressupport，则false ，但我不确定我是怎么做到的？

您可以选择使用?: conditional operator

public override string ToString()
{
    return string.Format("Disabled Student - ID: {0} (Age {1}) {2}", this.Number, this.Age, this.requiressupport ? "with support" : "without support");
}

根据布尔值输出不同的字符串
