Question

如何将2个字符串传递给Func并返回一个字符串？假设我想传递FirstName和LastName，结果应该像FirstName + LastName;

此外，我想将Func声明为属性。

请查看我的代码：

public class FuncClass
{
    private string FirstName = "John";
    private string LastName = "Smith";
    //TODO: declare FuncModel and pass FirstName and LastName.
}

public class FuncModel
{
    public Func<string, string> FunctTest { get; set; }
}

你能帮我解决这个问题吗？

这应该可以解决问题：

public class FuncModel
{
    //Func syntax goes <input1, input2,...., output>
    public Func<string, string, string> FunctTest { get; set; }
}

var funcModel = new FuncModel();
funcModel.FunctTest = (firstName, lastName) => firstName + lastName;
Console.WriteLine(funcModel.FuncTest("John", "Smith"));

委托Func作为财产
