Get var type value in C#

var temp = toCheck.GetData(DataFormats.FileDrop);

I have the code above in my program. toCheck is an IDataObjecct containing a file(image to be specific) path.

When I debug, I see the value stored under as such:
temp -> {string[1]}
[0] -> "C:\....rest of path"

Everything is correct but when I try to access the string inside, I cannot. If I use the toString() method it returns System.String[] but not the filepath.
Any suggestions on how I can retrieve the filepath inside of the variable?

temp -> {string[1]} Means that temp is an array of type string with one element.

[0] -> "C:\....rest of path" Means that the element at index 0 is equal to the path.

Since GetData returns the string array boxed as an object, you'll also have to unbox it first. Then you can simply access that element like this:

string[] strArr = temp as string[];
string s = temp[0];

I found the answer!

string[] arr = ((IEnumerable)temp).Cast<object>().Select(x => x.ToString()).ToArray();

Using the above statement you can go from type object to an array of string.
You need to have included using.System.Linq for it to work. 

 var temp = toCheck.GetData(DataFormats.FileDrop);
        string[] arr = ((IEnumerable)temp).Cast<object>().Select(x => x.ToString()).ToArray();
        string path = "";

        foreach(string a in arr)
            path = a;

This ended up being all the code if anybody is curious. I iterate over the array because otherwise it would skip the rest of the function when I debugged. Not sure what was causing this but this works. Thank you all for your help!

temp is an array of strings, that is why you are getting that. If you want to get the first string of the array then:

var mystring = temp[0];

That should do

Also you can check if the string[] has any string with:

if(temp.Length > 0) myString = temp[0];

where myString is a variable of type string
