{
Directory.CreateDirectory(folderPath1);
}
//Save the file in folder
int count = 1;
string file = "E:\\CoachingClassImages\\HeaderInfoImages\\Logo\\" + logo_picname;
string filename = Path.GetFileNameWithoutExtension(logo_location);
string extention = Path.GetExtension(filename);
string fileLocation1 = file;
if (File.Exists(file))
{
System.GC.Collect();
System.GC.WaitForPendingFinalizers();
string tempFileName = string.Format("{0}({1}){2}", filename, count++, extention);
File.Copy(fileLocation1, Path.Combine("E:\\CoachingClassImages\\HeaderInfoImages\\Logo\\", Path.GetFileName(tempFileName)), true);

//string folderPath1 = "E:\\CoachingClassImages\\HeaderInfoImages\\Logo\\";
string folderPath1 = @"d:\Logo\";
if (!Directory.Exists(folderPath1))
{
Directory.CreateDirectory(folderPath1);
}
//Save the file in folder
int count = 1;
string file = folderPath1 + "b.png";
string filename = Path.GetFileNameWithoutExtension(file);
string extention = Path.GetExtension(file);
string[] arrImages = Directory.GetFiles(@"d:\Logo", filename + "*" + extention);
string fileLocation1 = file;
if (File.Exists(file))
{
System.GC.Collect();
System.GC.WaitForPendingFinalizers();
count = arrImages.Length;
string tempFileName = string.Format("{0}({1}){2}", filename, count++, extention);
File.Copy(fileLocation1, Path.Combine(folderPath1, Path.GetFileName(tempFileName)), true);
}
else
{
File.Copy(fileLocation1, Path.Combine(folderPath1, Path.GetFileName(filename)), true);
}
