C# 遍历类属性 [英] C# Iterate through Class properties

问题描述

我目前正在设置我的类对象 Record 的所有值.

I'm currently setting all of the values of my class object Record.

这是我目前用来逐个属性地填充记录的代码.

This is the code that I'm using to populate the record at the moment, property by property.

// Loop through each field in the result set
for (int i = 0; i <= resultItems.Length; i++)
{

    Record newRecord = new Record()
    {
            itemtype =   resultItems[i - (fieldCount - 0)],
            itemdesc =   resultItems[i - (fieldCount - 1)],
            prodcode =   resultItems[i - (fieldCount - 2)],
            proddesc =   resultItems[i - (fieldCount - 3)],
            curstat =    resultItems[i - (fieldCount -4)],
            totfree =    resultItems[i - (fieldCount -5)],
            totphys =    resultItems[i - (fieldCount -6)],
            pcolgroup =  resultItems[i - (fieldCount -7)],
            scolgroup =  resultItems[i - (fieldCount -8)],
            totpo =      resultItems[i - (fieldCount - 9)],
            totso =      resultItems[i - (fieldCount - 10)],
            quality =    resultItems[i - (fieldCount - 11)],
            statusdesc = resultItems[i - (fieldCount - 12)],
            groupcode =  resultItems[i - (fieldCount - 13)],
            qualitydes = resultItems[i - (fieldCount - 14)],
            pcoldesc =   resultItems[i - (fieldCount - 15)],
            scoldesc =   resultItems[i - (fieldCount - 16)],
            pgroupdesc = resultItems[i - (fieldCount - 17)],
    };
}

是否可以在不硬编码所有属性名称的情况下动态遍历每个属性?

Can I iterate through each of the properties dynamically without hard coding all of the property names?

类似这样:

// Create new Record instance
Record newRecord = new Record();

for (int e = 0; e < propertyCount.Length - 1; e++)
{
    newRecord[fieldname] = resultItems[i - (fieldCount - e)];
}

推荐答案

您可以使用反射来做到这一点.据我了解，您可以枚举类的属性并设置值.您必须尝试一下，并确保您了解属性的顺序.有关此方法的更多信息，请参阅此 MSDN 文档.

You could possibly use Reflection to do this. As far as I understand it, you could enumerate the properties of your class and set the values. You would have to try this out and make sure you understand the order of the properties though. Refer to this MSDN Documentation for more information on this approach.

作为提示，您可以执行以下操作:

For a hint, you could possibly do something like:

Record record = new Record();

PropertyInfo[] properties = typeof(Record).GetProperties();
foreach (PropertyInfo property in properties)
{
    property.SetValue(record, value);
}

其中 value 是您要写入的值(因此来自您的 resultItems 数组).

Where value is the value you're wanting to write in (so from your resultItems array).
