如何从C#(2.0)中的属性获取属性的名称

我想做点什么

class Whotsit
{
    private string testProp = "thingy";

    public string TestProp 
    {
        get { return testProp; }
        set { testProp = value; }
    }

}

...

Whotsit whotsit = new Whotsit();
string value = GetName(whotsit.TestProp); //precise syntax up for grabs..

在哪里我期望价值等于“TestProp”

但我不能为我的生活找到正确的反射方法来编写GetName方法…

编辑：我为什么要这样做？我有一个类来存储从’name’,’value’表中读取的设置.这由基于反射的通用方法填充.我很想反写…

/// <summary>
/// Populates an object from a datatable where the rows have columns called NameField and ValueField. 
/// If the property with the 'name' exists,and is not read-only,it is populated from the 
/// valueField. Any other columns in the dataTable are ignored. If there is no property called
/// nameField it is ignored. Any properties of the object not found in the data table retain their
/// original values.
/// </summary>
/// <typeparam name="T">Type of the object to be populated.</typeparam>
/// <param name="toBePopulated">The object to be populated</param>
/// <param name="dataTable">'name,'value' Data table to populate the object from.</param>
/// <param name="nameField">Field name of the 'name' field'.</param>
/// <param name="valueField">Field name of the 'value' field.</param>
/// <param name="options">Setting to control conversions - e.g. nulls as empty strings.</param>

public static void PopulateFromNameValueDataTable<T>
        (T toBePopulated,System.Data.DataTable dataTable,string nameField,string valueField,PopulateOptions options)
    {
        Type type = typeof(T);
        bool nullStringsAsEmptyString = options == PopulateOptions.NullStringsAsEmptyString;

        foreach (DataRow dataRow in dataTable.Rows)
        {
            string name = dataRow[nameField].ToString();
            System.Reflection.PropertyInfo property = type.GetProperty(name);
            object value = dataRow[valueField];

            if (property != null)
            {
                Type propertyType = property.PropertyType;
                if (nullStringsAsEmptyString && (propertyType == typeof(String)))
                {
                    value = TypeHelper.EmptyStringIfNull(value);
                }
                else
                {
                    value = TypeHelper.DefaultIfNull(value,propertyType);
                }

                property.SetValue(toBePopulated,System.Convert.ChangeType(value,propertyType),null);
            }
        }
    }

进一步编辑：我只是在代码中,有一个Whotsit实例,我想得到’TestProp’属性的文本字符串.我知道这似乎有点奇怪,我可以使用文字“TestProp” – 或者在我的类的情况下使用数据表函数我将在PropertyInfos的foreach循环中.我只是好奇而已…

原始代码有字符串常量,我发现它很笨拙.
