var directory = new DirectoryInfo(HttpContext.Current.Server.MapPath(fileName));
if (directory.Exists == false)
{
directory.Create();

}

byte[] imageBytes = Convert.FromBase64String(ImageByteArray);
System.IO.FileStream file = System.IO.File.Create(HttpContext.Current.Server.MapPath("~/Images/Profile_Pic/"+ User_Id));

file.Write(imageBytes, 0, imageBytes.Length);
file.Close();

Well, then you must not have permission to access that directory.

You are trying to create a file with the same name as an existing directory. You probably forgot to append a file name or used the file name as directory name:

C#

string directoryName = "~/Images/Profile_Pic/" + User_Id;
// ...
System.IO.FileStream file = System.IO.File.Create(HttpContext.Current.Server.MapPath(directoryName + "/UserPic.ext"));

Thanks for your answer.but not happy and request to you please do not copy paste the code from somewhere to here,if u do not know the answer.

I have not copied code. I have typed it based on what you have posted to show an example how it must be done. Why should I not do?

It is an answer. It might not be the one you have expected but there is definitely a problem with your code:
You are checking if a directory exists, create it of not, and tries then to create a file with the same name. That won't work. There may be other errors too which are out of sight for readers of your question. But that does not make my solution not a answer.

This solution help me alot. Thanks man!
I keep thinking about setting permission for the directory but not the root caused. I forgot to set filename for it, it will directly Create file base on directory name --> Access Denied.
After verify directory exist, I used path.Combine between savePath and fileName --> Success
Here is my code

var savePath = @"C:\DataRawInfo";
if (!Directory.Exists(savePath))
{
    Directory.CreateDirectory(savePath);
}

var path = Path.Combine(savePath, defaultFileName);
File.WriteAllBytes(path, getFile);
Log.Information($"Store file:{defaultFileName} at {savePath} Success");
