How to merge two text TXT files together in C# .NET Framework

Merging TXT files is going to be a snap after you follow this ultra-quick tutorial.

We are going to start by installing our API client via Package Manager; simply run this command in your console.

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 2.2.0

Next step, invoke the function MergeDocumentTxt, and drop in your two files to be merged.

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;
namespace Example
{
public class MergeDocumentTxtExample
{
public void main()
{
// Configure API key authorization: Apikey
Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");
var apiInstance = new MergeDocumentApi();
var inputFile1 = new System.IO.Stream(); // System.IO.Stream | First input file to perform the operation on.
var inputFile2 = new System.IO.Stream(); // System.IO.Stream | Second input file to perform the operation on (more than 2 can be supplied).
try
{
// Merge Two Text (TXT) Files Together
Object result = apiInstance.MergeDocumentTxt(inputFile1, inputFile2);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling MergeDocumentApi.MergeDocumentTxt: " + e.Message );
}
}
}
}

Easy. The API will return us the merged TXT file. You may like some of our other functions, which encompass a very wide range of useful features; everything from format conversion to document editing.
