Various method to write file in C#

1- BufferedStream

1. public void UsingBufferedStream()  
2.   
3. {  
4.   
5. using (var file = File.Create(@"D:\MyTempFolder\temp1.txt"))  
6.   
7. {  
8.   
9. using (var b = new BufferedStream(file))  
10.   
11. {  
12.   
13. using (var writer = new StreamWriter(b))  
14.   
15. {  
16.   
17. writer.WriteLine("Hello Hamid.");  
18.   
19. }  
20.   
21. }  
22.   
23. }  
24.   
25. }   

 2 - MemoryStream

1. public void UsingMemoryStream()  
2. {  
3.     using (var memory = new MemoryStream())  
4.     {  
5.         using (var writer = new StreamWriter(memory))  
6.         {  
7.             writer.WriteLine("Hello Hamid");  
8.             writer.Flush();  
9.             using (var fileStream = File.Create(@"D:\MyTempFolder\temp2.txt "))  
10.             {  
11.                 memory.WriteTo(fileStream);  
12.             }  
13.         }  
14.     }  
15. }  

3- UsingFile()

1. public void UsingFile()  
2. {  
3.    string s=”Hello Hamid”;  
4.     File.WriteAllText(@"D:\MyTempFolder\temp3.txt ", s);  
5. }  

 4- UsingStreamWriter()

1. public static void UsingStreamWriter()  
2. {  
3.     using (var writer = File.CreateText(@"D:\MyTempFolder\temp4.txt "))  
4.     {  
5.         writer.WriteLine("Hello Hamid");  
6.     }  
7. }  

 5- UsingFileStream()

1. private void UsingFileStream()  
2. {  
3.     using (var target = File.Create(@"D:\MyTempFolder\temp5.txt "))  
4.     {  
5.         using (var writer = new StreamWriter(target))  
6.         {  
7.             writer.WriteLine("Hello Hamid ");  
8.         }  
9.     }  
10. }  

Call all the method in your place :

1. class Program  
2. {  
3. static void Main(string[] args)  
4. {  
5. string path = @"D:\MyTempFolder";  
6. FileHandler.CreateDirectory(path);  
7. FileHandler.UsingBufferedStream();  
8. FileHandler.UsingFile();  
9. FileHandler.UsingMemoryStream();  
10. FileHandler.UsingStreamWriter();  
11. FileHandler.UsingWithFileStream();  
12. Console.WriteLine("File created in all ways at path :"+ path);  
13. Console.ReadKey();  
14. }  
15.   
16. }  

Note Create Directory if not exist :

 

1. public static void CreateDirectory(string path)  
2.        {  
3.            try  
4.            {  
5.                if (!Directory.Exists(path))  
6.                {  
7.                    DirectoryInfo di = Directory.CreateDirectory(path);  
8.                }  
9.            }  
10.            catch (IOException ioex)  
11.            {  
12.                Console.WriteLine(ioex.Message);  
13.            }  
14.        }  

  

 

I hope it will help for our C# family developer .
