list转datatable

要将List转换为DataTable，可以使用以下代码实现：

public DataTable ListToDataTable<T>(List<T> list)
{
    DataTable dataTable = new DataTable();
    PropertyInfo[] properties = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);

    foreach (PropertyInfo property in properties)
    {
        dataTable.Columns.Add(property.Name, property.PropertyType);
    }

    foreach (T item in list)
    {
        DataRow dataRow = dataTable.NewRow();

        foreach (PropertyInfo property in properties)
        {
            dataRow[property.Name = property.GetValue(item);
        }

        dataTable.Rows.Add(dataRow);
    }

    return dataTable;
}

这个方法接受一个List作为参数，并使用反射来获取List中对象的属性信息。然后，它创建一个DataTable对象，并根据属性信息添加列。接下来，它遍历List中的每个对象，创建一个DataRow对象，并将属性值赋给相应的列。最后，将DataRow添加到DataTable中，最终返回转换后的DataTable。<span class="em">1</span><span class="em">2</span>
