c# - 使用字典键(作为字符串)在构造函数中设置变量

Question

与其多次重载类构造函数，不如传入一个 Dictionary 来动态设置变量。

// Class definition
public class Project
{
    public DateTime LastModified;
    public string LoanName;
    public string LoanNumber;
    public int LoanProgram;
    public string ProjectAddress;
    ...

    // Project class constructor
    public Project(Dictionary<string, object> Dict)
    {
        foreach (KeyValuePair<string, object> entry in Dict)
        {
            // ie, when the Key is "LoanName", this.LoanName is set
            this.(entry.Key) = entry.Value;   // <-- Does not compile, obviously
        }
    }
}

// application code
...
Dictionary<string, object> dict = new Dictionary<string,object>();
dict.Add("LoanName", "New Loan Name");
dict.Add("LoanProgram", 1);
dict.Add("ProjectAddress", "123 Whatever Way");
Project p = new Project(dict);
...

在构造函数中，有没有办法使用Dictionary Key(字符串)来确定要设置的类成员？这可以通过某种方式使用反射来完成吗？

字段已经公开了...为什么不直接使用对象初始化语法呢？

var p = new Project() {
    LoanName = "New Loan Name",
    LoanProgram = 1,
    ProjectAddress = "123 Whatever Way"
};
