+## Create .ipynb file using selwct .net Enviroment and select C# in cell for execution
+
+### Import nuget package
+
+```cs
+#r "nuget: Microsoft.Data.Analysis" 
+```
+
+### Import namespace
+
+```cs
+using System;
+using System.Collections.Generic;
+using Microsoft.Data.Analysis;
+```
+
+### Create class
+
+```cs
+public class RedirectEntry
+{
+    public string WebsiteUrl { get; set; }
+    public string RedirectUrl { get; set; }
+    public string Status => IsValid ? "✅" : "❌";
+    public bool IsValid { get; set; }
+}
+
+var data = new List<RedirectEntry>
+{
+    new RedirectEntry
+    {
+        WebsiteUrl = "https://codefrydev.in/Updates",
+        RedirectUrl = "https://codefrydev.in/",
+        IsValid = true
+    },
+};
+
+```
+
+### Create Generic Function for anytype of list incection
+
+```cs
+DataFrame ShowTable<T>(List<T> items)
+{
+    var properties = typeof(T).GetProperties();
+    List<DataFrameColumn> columns = new();
+
+    foreach (string header in properties.Select(p => p.Name))
+    {
+        columns.Add(new StringDataFrameColumn(header, new List<string>())); // Read as string
+    }
+    foreach(var item in items)
+    {
+        for (int i = 0; i < properties.Length; i++)
+        {
+            var values = properties.Select(p => p.GetValue(item)?.ToString() ?? "").ToList();
+            ((StringDataFrameColumn)columns[i]).Append(values[i]);
+        }
+    }
+    return new DataFrame(columns);
+}
+```
+
+### Simply call the function in next cell without any commas or stuff
+
+```cs
+ShowTable(data)
+```
