Delay response while converting Image?

Hi everyone I have an issue I am making API on .net core when I call data in this there is filed image which return image path, I want to convert it into byte64, when I converted then there is a lot of time to give response below is my code.

I want a response in no time,

var data = await Task.Run(() => context.GetStoreProc.FromSqlRaw("EXECUTE dbo.Nstp_GetTeamBy_ID {0}", ManagerID).Select(x => new TeamManagerResponse
{
DepartmentName = x.DepartmentName,
DesignationDesc = x.DesignationDesc,
EmailAdd = x.EmailAdd,
EmpImg = DataHelper.ConvertImageToByteArray(x.EmpImg), // below is this method
EmpName = x.EmpName
}).ToListAsync());
return data;

public static string ConvertImageToByteArray(string Image_Path)
{
string imgPathFinal = "";
var imgPath = System.Reflection.Assembly.GetEntryAssembly().Location;
int location = imgPath.LastIndexOf("\\bin");
imgPathFinal = imgPath.Substring(0, location) + Image_Path;
byte[] imageByteArray = null;
if (File.Exists(imgPathFinal))
{
//byte[] result = DataHelper.ConvertImageToByteArray(imgPathFinal);
FileStream fileStream = new FileStream(imgPathFinal, FileMode.Open, FileAccess.Read);
using (BinaryReader reader = new BinaryReader(fileStream))
{
imageByteArray = new byte[reader.BaseStream.Length];
for (int i = 0; i < reader.BaseStream.Length; i++)
imageByteArray[i] = reader.ReadByte();
}
return Convert.ToBase64String(imageByteArray, 0, imageByteArray.Length);
}
else
{
return imgPathFinal;
}
}

please help me

It is slow because you are reading single byte from your file and storing it in a array, please be generally aware that file already consist of sequence of bytes, so you can just read all the bytes from file and do your stuff, like

var imageBytes = File.ReadAllBytes(path);
