IEnumerableタイプを直接DataTableに変換
RT,直接上コード
public static class IEnumerableExtensions
{
public static DataTable AsDataTable(this IEnumerable data)
{
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(typeof(T));
var table = new DataTable();
foreach (PropertyDescriptor prop in properties)
table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType);
foreach (T item in data)
{
DataRow row = table.NewRow();
foreach (PropertyDescriptor prop in properties)
row[prop.Name] = prop.GetValue(item) ?? DBNull.Value;
table.Rows.Add(row);
}
return table;
}
}
