Introduction:
This article explain you to convert List Items in C# to DataTable
Description:
Below C# code is used to convert any list items to datatable using a generic method
HTML Java Script CSS:
To implement this we need to write the code like as shown below

C# Code
using AngularJSCURD.Models;
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Reflection;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace AngularJSCURD.Pages
{
public partial class ListToDataSet : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
BindGrid();
}
public void BindGrid()
{
DataTable DTable = new DataTable();
List<Employee> objEmployeeList = new List<Employee>();
objEmployeeList.Add(new Employee { Id = 1, Name = "Muhammad Asif", Gender = "Male", Salary = 2000, DeptId = 10 });
objEmployeeList.Add(new Employee { Id = 2, Name = "Muhammad Nizam", Gender = "Male", Salary = 3000, DeptId = 20 });
objEmployeeList.Add(new Employee { Id = 3, Name = "Muhammad Arif", Gender = "Male", Salary = 4000, DeptId = 30 });
objEmployeeList.Add(new Employee { Id = 4 Name = "Muhammad Azhar", Gender = "Male", Salary = 5000, DeptId = 40 });
DTable = ConvertToDataTable<Employee>(objEmployeeList);
GvEmployee.DataSource = DTable;
GvEmployee.DataBind();
}
}
}Method Used to Convert List To DataTable :
public DataTable ConvertToDataTable<T>(List<T> items)
{
DataTable dataTable = new DataTable(typeof(T).Name);
PropertyInfo[] Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);
foreach (PropertyInfo prop in Props)
{
dataTable.Columns.Add(prop.Name);
}
foreach (T item in items)
{
var values = new object[Props.Length];
for (int i = 0; i < Props.Length; i++)
{
values[i] = Props[i].GetValue(item, null);
}
dataTable.Rows.Add(values);
}
return dataTable;
}DEMO
