C# mail merge

Mail merge in C#!

Mail merge is a process of combining a template document with data from a data source to create a new document with the data inserted into the template. In C#, you can achieve mail merge using various libraries and techniques. Here are a few approaches:

1. StringTemplate: StringTemplate is a popular open-source library for mail merge in C#. It allows you to define a template with placeholders and then merge data into the template using a simple syntax.
2. MailMerge: MailMerge is a.NET library that provides a simple way to perform mail merge operations. It supports various data sources, including databases, XML files, and CSV files.
3. DocX: DocX is a.NET library that allows you to create and manipulate Word documents. You can use it to perform mail merge operations by replacing placeholders in a template document with data from a data source.
4. iTextSharp: iTextSharp is a.NET library that allows you to create and manipulate PDF documents. You can use it to perform mail merge operations by replacing placeholders in a template document with data from a data source.

Here's an example of how you can use StringTemplate to perform a mail merge in C#:

using StringTemplate;

// Define the template
string template = "Hello, {{name}}! Your order number is {{orderNumber}}.";

// Define the data
Dictionary<string, object> data = new Dictionary<string, object>
{
    { "name", "John Doe" },
    { "orderNumber", "12345" }
};

// Create a new StringTemplate engine
StringTemplateEngine engine = new StringTemplateEngine();

// Compile the template
StringTemplate templateObject = engine.Compile(template);

// Merge the data into the template
string result = templateObject.Render(data);

// Output the result
Console.WriteLine(result);

This code defines a template with placeholders for name and orderNumber, and then merges the data into the template using the Render method. The resulting string is then output to the console.

Similarly, you can use MailMerge, DocX, or iTextSharp to perform mail merge operations in C#. Each library has its own syntax and features, so be sure to check the documentation for the library you choose to use.
