C#

static    public void getSize(string pathLocation)
{

    DirectoryInfo dInfo = new DirectoryInfo(pathLocation);
    sizeOfDirKb = DirectorySize(dInfo, true) / (1024);


    adminProcess = new System.Diagnostics.ProcessStartInfo();

    TotalSizeOfFolderByte = sizeOfDirKb / (1024 * 1024);

    if (TotalSizeOfFolderByte < 100)
    {
        TotalSizeOfFolder = Math.Floor(TotalSizeOfFolderByte * 100) / 100;

    }
    else if (TotalSizeOfFolderByte >= 100)
    {
        TotalSizeOfFolder = Math.Floor(TotalSizeOfFolderByte);
    }
}

static int i=0;

static   double DirectorySize(DirectoryInfo dInfo, bool includeSubDir)
{
    totalSize = dInfo.EnumerateFiles()//double
                .Sum(file => file.Length);//double
    Total = Total + totalSize / 1024 / 1024 / 1024;//double
    total1[i] = Total;//double

    if (includeSubDir)
    {
        totalSize += dInfo.EnumerateDirectories()
                 .Sum(dir => DirectorySize(dir, true));

    }

    return totalSize;
}

What I have tried:

Multi thread and multi task but still can not.

The answer depends on what platform: UWP; WPF; Windows forms; Net Core; Net Framework...

Windows Forms has the fewest short-cuts to threading; this should help:

Yeah bro. But I try it already but when I apply it to my function it doesn't work. When I get thread to array and run it with function with loop. It doesn't work.

[no name] 2-Dec-19 11:20am

Try harder.

CHill60 2-Dec-19 11:47am

"it doesn't work" does not help us to help you. You are really making this hard work for us

Tra22 2-Dec-19 19:40pm

Why?

CHill60 3-Dec-19 5:37am

Why? Because you are not being clear about your problem. You need to learn to describe problems accurately and fully. It's hard work for us to keep asking you questions and asking for clarification. Most people will just stop bothering.

Solution 3

getsize for multiple path location at same time, use c# inbuilt TPL(parallel task library)

Parallel.Invoke(
            () =>
            {
                //code for getsize1
            },

            () =>
            {
                //code for getsize2
            },

            () =>
            {
                //code for getsizeN
            }

i hope this will help.

Could we use loop on parallel. Invoke? Because the function getSize is alot and we can not know how much is it.

Tra22 2-Dec-19 18:25pm

Mean that the location path for get size store in arraylist

[no name] 3-Dec-19 0:34am

something like below
var collectionofpaths = new List<string>();
var actions = new List<action>();
foreach (var path in collectionofpaths)
{
actions.Add(() => getsize(path));
}

Parallel.Invoke(actions.ToArray());

Tra22 3-Dec-19 5:13am

I will try it.And tell you about it can or not.Too much thanks bro.

Tra22 3-Dec-19 5:45am

The problems is that the function is not calculate one by one.But it's total all size of function.Example getSize1=100GB ,getSize2=1000Gb,getSize3=10000GB but it's not show like that.But it shows with 11100GB(Total all function)

[no name] 3-Dec-19 6:20am

if i remember well you are keeping global variable 'TotalSizeOfFolder ' that why you get total size of all. to solve this problem, you need to return size value for each getsize method, then TPL may not work, you can use another option Task, which start new thread for each operation.

dictionary with each path and value 0 can be defined in starting. then at the end you will get size for each path.
var collectionofpaths = new Dictionary<string, int="">();
List<task> tasks = new List<task>();
foreach (var f in collectionofpaths)
{
tasks.Add(System.Threading.Tasks.Task.Factory.StartNew(() => collectionofpaths[f.Key] = getsize(f.Key)));
}

System.Threading.Tasks.Task.WaitAll(tasks.ToArray());
