Check if a file exist with C# using SharePoint Client Object Modal
Hi Guys, if you need to test using C# if a file exist in a certain SharePoint document library ? You can use SharePoint Client Object Modal.
Here, I wrote a C# console application which uses behind the scene the built in SharePoint web services.
using System;
using Microsoft.SharePoint.Client;
namespace TestExist
{
class Program
{
static void Main(string[] args)
{
string Web = @”https://domain/sitecollection/“;
string FileName = @”/Sitecollection/Records/file.txt”;
ClientContext clientContext = new ClientContext(Web);
Web site = clientContext.Web;
if (TryGetFileByServerRelativeUrl(site, FileName)) Console.WriteLine(“File exists”); elseConsole.WriteLine(“File does not exist”);
Console.ReadLine();
}
public static bool TryGetFileByServerRelativeUrl(Web web, string serverRelativeUrl)
{
var ctx = web.Context;
try
{
File file = web.GetFileByServerRelativeUrl(serverRelativeUrl);
ctx.Load(file);
ctx.ExecuteQuery();
return true;
}
catch (Microsoft.SharePoint.Client.ServerException ex)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine(ex.Message);
if (ex.ServerErrorTypeName == “System.IO.FileNotFoundException”)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine(ex.Message);
return false;
}
return false;
}
catch (Exception exp)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine(exp.Message);
return false;
}
}
}
}
