Asp.net word mail merge c

A classic!

In ASP.NET, you can perform a mail merge using the System.Text.RegularExpressions namespace and the String.Format method. Here's an example:

Step 1: Prepare your data

Create a dataset or a list of objects that contains the data you want to merge. For example:

List<MyData> data = new List<MyData>();
data.Add(new MyData { Name = "John", Address = "123 Main St" });
data.Add(new MyData { Name = "Jane", Address = "456 Elm St" });

Step 2: Create a template

Create a template file (e.g., template.docx) with placeholders for the data. For example:

Dear {Name},

Your address is: {Address}

Best regards,
[Your Name]

Step 3: Perform the mail merge

Use the String.Format method to replace the placeholders with the actual data:

foreach (MyData item in data)
{
    string template = File.ReadAllText("template.docx");
    string merged = String.Format(template, item.Name, item.Address);
    // Save the merged document to a file or send it via email
    File.WriteAllText("output.docx", merged);
}

In this example, the String.Format method replaces the {Name} and {Address} placeholders with the actual values from the MyData object.

Step 4: Save or send the merged document

Save the merged document to a file or send it via email using your preferred method.

Here's the complete code:

using System;
using System.Collections.Generic;
using System.IO;
using System.Text.RegularExpressions;

public class MyData
{
    public string Name { get; set; }
    public string Address { get; set; }
}

public class MailMerge
{
    public void PerformMailMerge(List<MyData> data)
    {
        foreach (MyData item in data)
        {
            string template = File.ReadAllText("template.docx");
            string merged = String.Format(template, item.Name, item.Address);
            File.WriteAllText("output.docx", merged);
        }
    }
}

Note that this is a basic example, and you may need to adjust the code to fit your specific requirements. Additionally, if you're working with complex documents or large datasets, you may want to consider using a dedicated mail merge library or a more advanced templating engine.
