Getting The folder From the application direcotry

When we use the below code, automatically it will locate the exe file location only. Our exe will be in bin directory only. When deploy the exe under D:/Muthu, then the file will be placed under D:/Muthu folder. If u want to place the file under D:/Muthu/Tech then concat the strAppPath with Tech folder aswell. (string strAppPath = Application.StartupPath+ \\Tech;)
string strAppPath = Application.StartupPath;

Not this i need i have written like this

path = System.AppDomain.CurrentDomain.BaseDirectory;

but this is saving the file in bin directory but i need to save i a seperate folder in which my application is running.

To create the folder from application:
 
if (!Directory.Exists(@"D:\Muthu\"))
{
Directory.CreateDirectory(@"D:\Muthu\");
}
//To open new save dialogue popup window:
saveFileDialog1.InitialDirectory = @"D:\Muthu\Tech\";
saveFileDialog1.Title = "Sample file";
saveFileDialog1.Filter = "All files|*.*|Text Documents (*.txt)|*.txt";
saveFileDialog1.ShowDialog();
//To save the file without opening a popup window
using (SaveFileDialog saveFileDialog2 = new SaveFileDialog())
{
saveFileDialog2.FileName = @"D:\Muthu\Tech\Sample.txt";
//To write the string value into the new text file
File.WriteAllText(saveFileDialog2.FileName, strValue);
}
