DataTable 数据集灵活好用,开发过程中怎么把其他类型的数据集转换成DataTable也就成了很多人想的问题
public DataTable ConvertToDataTable<T>(IList<T> i_objlist)
{
if (i_objlist == null || i_objlist.Count <= 0)
{
return null;
}
DataTable dt = new DataTable(typeof(T).Name);
DataColumn column;
DataRow row;
System.Reflection.PropertyInfo[] myPropertyInfo = typeof(T).GetProperties(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance);
foreach (T t in i_objlist)
{
if (t == null)
{
continue;
}
row = dt.NewRow();
for (int i = 0, j = myPropertyInfo.Length; i < j; i++)
{
System.Reflection.PropertyInfo pi = myPropertyInfo[i];
string name = pi.Name;
if (dt.Columns[name] == null)
{
column = new DataColumn(name, pi.PropertyType);
dt.Columns.Add(column);
}
row[name] = pi.GetValue(t, null);
}
dt.Rows.Add(row);
}
return dt;
}
