This post describes how to convert generic list collection to datatable
First Import following namespace
using System.Xml;
using System.IO;
using System.ComponentModel;
Setp 1 :First Create one Entity
public class City
{
public string CityCode { get; set; }
public string CityName { get; set; }
}
Step 2: Create Method to bind List Collection and Convert to Datatable
public void BindCityFromXML()
{
string filepath = @"C:\city.xml";
DataSet ds = new DataSet();
ds.ReadXml(filepath);
List<City> CityColl= new List<City>();
DataTable CityTable = new DataTable();
foreach (DataRow dr in ds.Tables[0].Rows)
{
City ct = new City();
ct.CityCode = dr["code"].ToString();
ct.CityName = dr["Name"].ToString();
CityColl.Add(ct);
}
CityTable = ConvertTo<City>(CityColl);
}
Step 3: Write Following Method
public DataTable ConvertTo<T>(IList<T> lst)
{
DataTable tbl = CreateTable<T>();
Type entType = typeof(T);
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(entType);
foreach (T item in lst)
{
DataRow row = tbl.NewRow();
foreach (PropertyDescriptor prop in properties)
{
row[prop.Name] = prop.GetValue(item);
}
tbl.Rows.Add(row);
}
return tbl;
}
public DataTable CreateTable<T>()
{
Type entType = typeof(T);
DataTable tbl = new DataTable(entType.Name);
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(entType);
foreach (PropertyDescriptor prop in properties)
tbl.Columns.Add(prop.Name, prop.PropertyType); return tbl;
}

}

}
return tbl;
}
public DataTable CreateTable<T>()
{
Type entType = typeof(T);
DataTable tbl = new DataTable(entType.Name);
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(entType);
foreach (PropertyDescriptor prop in properties)
tbl.Columns.Add(prop.Name, prop.PropertyType); return tbl;
}
