C# create file with text

Question

I have problem with the FileStream. I want to create a file with my custom name, but it doesn't work. What I doing wrong ?

string nameoftest = Console.ReadLine()+".txt";
string path = "C:\C#test\" + nameoftest;
Console.WriteLine(path);
FileStream create = new FileStream(@"path", FileMode.OpenOrCreate, FileAccess.ReadWrite);
StreamWriter sw = new StreamWriter(create);

Answer 1

There are some mistakes in your code.

• You should specify a valid path

• You should pass path parameter for FileStream

• You could use sw.WriteLine after declaring StreamWriter

• It could be better to use using blocks to dispose streams when you finish your job

The code looks like

string nameoftest = Console.ReadLine() + ".txt";
string path = @"C:\" + nameoftest;
Console.WriteLine(path);
using (var fileStream = new FileStream(path, FileMode.OpenOrCreate, FileAccess.ReadWrite))
using (var sw = new StreamWriter(fileStream))
{
    sw.WriteLine("WriteSomething");
}

Answer 2

基本上，@符号放错位置

错误分为两行：

  

string path =“C：\ C＃test \”+ nameoftest;

应该是

  

string path = @“C：\ C＃test \”+ nameoftest;

第二个错误是：

  

FileStream create = new FileStream（@“path”，FileMode.OpenOrCreate，   FileAccess.ReadWrite）;

应该是

  

FileStream create = new FileStream（path，FileMode.OpenOrCreate，   FileAccess.ReadWrite）;
