怎样才能像C＃中的字符串一样处理不同类型的数组（字符串，整数，字符）？

Question

I have a collection of objects that each object would contains a different kind of array (string[],int[],char[]) or even single value as different types.

I want to get the values of each array as single format such as string and convert it to a comma text value.

here is the code that manipulates an object of collection as "UInt16[]"

UInt16[] arrCapabilities = (UInt16[])(queryObj["Capabilities"]);
foreach (UInt16 arrValue in arrCapabilities)
{
    Console.WriteLine("Capabilities: {0}", arrValue);
}

Answer 1

You could try using the following code:

IEnumerable array = queryObj["Capabilities"] as IEnumerable;
if(array != null)
{
    foreach(var item in array)
    {
        Console.WriteLine(item.ToString());
    }
}
else
{
    Console.WriteLine(queryObj["Capabilities"].ToString());
}

Answer 2

您可以使用LINQ将数组转换为IEnumerable字符串：

var myStrings = from c in arrCapabilities select c.ToString();

Answer 3

To Expand on Daniels answer and get the csv string you are after:

IEnumerable array = queryObj["Capabilities"] as IEnumerable;
if(array != null)
{
     var csvString = String.Join(", ", array.Cast<object>().Select(x => x.ToString()));
     Console.WriteLine(csvString);
}
else
{
    Console.WriteLine(queryObj["Capabilities"].ToString());
}

Answer 4

Does this help?

void WriteToConsole<T>(IEnumerable<T> items)
{
    foreach (var item in items)
        Console.WriteLine("Capabilities: " + item);
}
