堆棧跟蹤:
[NotSupportedException異常:Collection是 只讀]
System.SZArrayHelper.Clear()56

我的代碼是: 型號:
namespace TestArrays.Models

public class Person

public CategoriesRow[] Categories { get; set; }
public Person()
{
Categories = new CategoriesRow[1];
Categories[0] = new CategoriesRow();

我懷疑這個問題涉及到什麼是從'<%的foreach(在Model.Categories VAR類)'返回。更確切地說,'Model.Categories'部分,您的代碼片段不會顯示定義。也許澄清? – 2010-07-13 06:46:47
