C# 数据集错误

Question

我有以下代码：

namespace Company.Project.DataProvider
{    
    partial class MyDataSet
    {
        partial class MyDataTable
        {
        }
    }
}

namespace Company.Project.DataProvider.MyDataSetTableAdapters
{
    public partial class MyTableAdapter
    {
        public int CommandTimeout
        {
            set
            {
                for (int i = 0; (i < this.CommandCollection.Length); i = (i + 1))
                {
                    if ((this.CommandCollection[i] != null))
                    {
                        this.CommandCollection[i].CommandTimeout = value;
                    }
                }
            }
        }
    }

    protected void ObjectDataSource1_ObjectCreating
        (object sender, ObjectDataSourceEventArgs e)
    {
        Company.Project.DataProvider.MyDataSetTableAdapters.MyTableAdapter =  
            (Company.Project.DataProvider.MyDataSetTableAdapters.MyTableAdapter)
              e.ObjectInstance;
        // Set command timeout to 2 minutes
        adapter.CommandTimeout = 120;
    }
}

当我运行上面的代码时，我收到以下错误：

类型或命名空间名称“Company” 找不到（您是否缺少 使用指令或程序集 参考？）

我的代码有什么问题？

现在，我收到以下错误。

CS1061: 'CariPeriyot.Rapor.TEST_TumRaporlar' does not contain a definition 
for 'CommandCollection' and  no extension method 'CommandCollection' 
accepting a first argument of type 'CariPeriyot.Rapor.TEST_TumRaporlar' 
could be found (are you missing a using directive or an assembly reference?)

Source Error:

Line 7:         set
Line 8:         {
Line 9:           for (int i = 0; (i < this.CommandCollection.Length); i = (i + 1))
Line 10:           {
Line 11:              if ((this.CommandCollection[i] != null))

Answer 1

Company.Project.DataProvider.MyDataSetTableAdapters.MyTableAdapter 引用一个类，而不是一个变量，因此赋值失败。

尝试：

Company.Project.DataProvider.MyDataSetTableAdapters.MyTableAdapter foo = ...

Answer 2

将以下代码替换

Company.Project.DataProvider.MyDataSetTableAdapters.MyTableAdapter =  
   (Company.Project.DataProvider.MyDataSetTableAdapters.MyTableAdapter)
    e.ObjectInstance;

为：

Company.Project.DataProvider.MyDataSetTableAdapters.MyTableAdapter adapter =  
   (Company.Project.DataProvider.MyDataSetTableAdapters.MyTableAdapter)
    e.ObjectInstance;
