Search File Exist or Present in Directory Windows Application Using C#.Net

This article will show you how you can search a file existence it presence in a directory or folder in windows application using c#.net.

Some of my previous articles are as follows: Get List Of All Files Present in Directory In Windows Application Using C#.Net, Bind DataGridView With DataTable Using C#.Net In Windows Application, Display DataGridView Selected Row Values To Second From Using C# In Windows Application, Bind DataGridView With Sql Server Table Using C#.Net In Windows Application, How To Convert Text Into Image In C# In Windows Application, Detecting Ctrl+ V Key Pressed Or Stroke Using C# & VB.Net In Windows Application, Read Outlook Email Subject Using c#.

So for this article first we will create a new windows application and add some button and textbox control on form. Your form will look as shown below:

 

After this we will create click event of button and add the below code on button click event.

private void button1_Click(object sender, EventArgs e)         {             string[] filePaths = Directory.GetFiles(txtDirectoryPath.Text);             string filename = txtFileName.Text;             foreach (string item in filePaths)             {                 if (item.Contains(filename))                 {                     lblmessage.Text = "File Exists";                     break;                 }                 else                 {                     lblmessage.Text = "File NOT Exists";                 }             }         }

In above code first I have fetched all the files present in the provided directory and then I have applied look to checked and every file one by one weather the file is present in the collection or not. 

If it’s found then it will show the message “File Exists” otherwise it will display “File Not Found”.

Now we have done run the application to check the output. First we will check the file directory.

 Now we will provide directory path and file name. 

 Now we will provide invalid file name.
