C# Get file size of array with paths

I am new to arrays and I want to display the size (in MB) of multiple files into a textBox. The paths to the files are in an array.

var Files = Directory.GetFiles(Path, "*" + filetype, SearchOption.AllDirectories);

I saw this code in another post to get the size of a file:

long length = new System.IO.FileInfo(file).Length;

How can I add all of the file sizes to an int/string and write them into the textBox?

c# arrays file filesize

If i understand you correctly, just use Linq Select and string.Join

var results = Directory.GetFiles(Path, "*" + filetype, SearchOption.AllDirectories)
 .Select(file => new FileInfo(file).Length);

 TextBox1.Text = string.Join(", ", results);

if you want to sum them, just use Enumerable.Sum

 TextBox1.Text = $"results.Sum():N3";

Update

public static class MyExtension

 public enum SizeUnits
 
 Byte, KB, MB, GB, TB, PB, EB, ZB, YB
 

 public static string ToSize(this Int64 value, SizeUnits unit)
 
 return (value / (double)Math.Pow(1024, (Int64)unit)).ToString("0.00");
 


 TextBox1.Text = results.Sum().ToSize();

The below code may work to you.

var FilesAndSizes = Directory.GetFiles(Path, "*" + filetype, SearchOption.AllDirectories).Select(item => new KeyValuePair<string,int>(item, new System.IO.FileInfo(item).Length));

Using Directory.EnumerateFiles you're able to calculate the total size while only traversing the array once.

To get the total size for all files of an extension:

long totalSizeInBytes = 0;
foreach(var file in Directory.EnumerateFiles(Path, "*" + filetype, SearchOption.AllDirectories))
 
 totalSizeInBytes += new FileInfo(file).Length;

To get a list of all file sizes:

var results = Directory.EnumerateFiles(Path, "*" + filetype, SearchOption.AllDirectories)
 .Select(file => new FileInfo(file).Length);

TextBox1.Text = string.Join(", ", results);

i think that DirectoryInfo object cuold be smarter for your case istead of Directory object.

Look at that example:

public static void Main()

 string filetype = ".jpg";

 // Make a reference to a directory.
 DirectoryInfo di = new DirectoryInfo("c:\");
 // Get a reference to each file in that directory.
 FileInfo fiArr = di.GetFiles("*" + filetype, SearchOption.AllDirectories);
 // Display the names and sizes of the files.
 Console.WriteLine("The directory 0 contains the following files:", di.Name);
 foreach (FileInfo f in fiArr)
 Console.WriteLine("The size of 0 is 1 bytes.", f.Name, f.Length);

the GetFiles method returns an array of FileInfo objects, where you can find the filesize.

Parameters:

I this example i'm writing to console output but in the same way you can add the text to your textbox.

 mytexbox.Text += String.Format("The size of 0 is 1 bytes.rn", f.Name, f.Length);

If you don't want to add complexity by using LINQ and want to practice with arrays:

var Files = Directory.GetFiles(Path, "*" + filetype, SearchOption.AllDirectories);

long length = 0;

for (int i = 0; i < Files.Length; i++)

 length += new FileInfo(Files[i]).Length;

If you don't want to add complexity by using LINQ and want to practice with arrays:

var Files = Directory.GetFiles(Path, "*" + filetype, SearchOption.AllDirectories);

long length = 0;

for (int i = 0; i < Files.Length; i++)

 length += new FileInfo(Files[i]).Length;

The below code may work to you.

var FilesAndSizes = Directory.GetFiles(Path, "*" + filetype, SearchOption.AllDirectories).Select(item => new KeyValuePair<string,int>(item, new System.IO.FileInfo(item).Length));

Using Directory.EnumerateFiles you're able to calculate the total size while only traversing the array once.

To get the total size for all files of an extension:

long totalSizeInBytes = 0;
foreach(var file in Directory.EnumerateFiles(Path, "*" + filetype, SearchOption.AllDirectories))
 
 totalSizeInBytes += new FileInfo(file).Length;

To get a list of all file sizes:

var results = Directory.EnumerateFiles(Path, "*" + filetype, SearchOption.AllDirectories)
 .Select(file => new FileInfo(file).Length);

TextBox1.Text = string.Join(", ", results);

i think that DirectoryInfo object cuold be smarter for your case istead of Directory object.

Look at that example:

public static void Main()

 string filetype = ".jpg";

 // Make a reference to a directory.
 DirectoryInfo di = new DirectoryInfo("c:\");
 // Get a reference to each file in that directory.
 FileInfo fiArr = di.GetFiles("*" + filetype, SearchOption.AllDirectories);
 // Display the names and sizes of the files.
 Console.WriteLine("The directory 0 contains the following files:", di.Name);
 foreach (FileInfo f in fiArr)
 Console.WriteLine("The size of 0 is 1 bytes.", f.Name, f.Length);

the GetFiles method returns an array of FileInfo objects, where you can find the filesize.

Parameters:

I this example i'm writing to console output but in the same way you can add the text to your textbox.

 mytexbox.Text += String.Format("The size of 0 is 1 bytes.rn", f.Name, f.Length);
