Question

我知道我C#类财产的名称。是否可能利用思考来确定这一财产的价值?

For example, say I know the name of a property is string propertyName = "first_name";. And there actaully exists a property called first_name. Can I set it using this string?

是的,你可以使用思考——仅用。 http://msdn.microsoft.com/en-us/library/xb5d1f1.aspx” rel=“noreferer”SetValue。样本:

using System;

class Person
{
    public string Name { get; set; }
}

class Test
{
    static void Main(string[] arg)
    {
        Person p = new Person();
        var property = typeof(Person).GetProperty("Name");
        property.SetValue(p, "Jon", null);
        Console.WriteLine(p.Name); // Jon
    }
}

If it s not a public property, you ll need to specify BindingFlags.NonPublic | BindingFlags.Instance in the GetProperty call.
