DataSet
, DataTable
and linq expression are common DataSource
values of a DataGridView
.
Now in reverse, is it possible to pass/bind a DataGridView
record to DataSet
or DataTable
?
Thanks
Got this Best Answer from Csharp Corner:
public DataTable LINQToDataTable<T>(IEnumerable<T> varlist)
{
DataTable dtReturn = new DataTable();
// column names
PropertyInfo[] oProps = null;
if (varlist == null)
return dtReturn;
foreach (T rec in varlist)
{
// Use reflection to get property names, to create table, Only first
// time, others will follow
if (oProps == null)
{
oProps = ((Type)rec.GetType()).GetProperties();
foreach (PropertyInfo pi in oProps)
{
Type colType = pi.PropertyType;
if ((colType.IsGenericType) &&
(colType.GetGenericTypeDefinition() == typeof(Nullable<>)))
{
colType = colType.GetGenericArguments()[0];
}
dtReturn.Columns.Add(new DataColumn(pi.Name, colType));
}
}
DataRow dr = dtReturn.NewRow();
foreach (PropertyInfo pi in oProps)
{
dr[pi.Name] = pi.GetValue(rec, null)==null ? DBNull.Value
: pi.GetValue(rec,null);
}
dtReturn.Rows.Add(dr);
}
return dtReturn;
}
Example: To use this method, just use the following code sample:
var vrCountry = from country in objEmpDataContext.CountryMaster
select new {country.CountryID,country.CountryName};
DataTable dt = LINQToDataTable(vrCountry);
Thanks
