c# - 使用 for 循环添加 IList

Question

我的结果列表为

var attributeresult= " some list of items......";

现在我正在尝试循环表单结果并添加到 IList。但我只得到最后插入值，但我想获取所有值。

 IList<DynamicColumn> idynamicttableColumns = new List<DynamicColumn>();
 DynamicColumn dynamictableColumns = new DynamicColumn();


 for (int i = 0; i < attributeresult.Count(); i++)
                        {
                            dynamictableColumns.Name = attributeresult.ElementAt(i).AttributeName;
                            dynamictableColumns.Type = attributeresult.ElementAt(i).AttributeSqlType;
                            dynamictableColumns.IsNullable = false;
                            idynamicttableColumns.Add(dynamictableColumns);

                        }

我必须用 for 循环完成，而不是用 for each 循环。

Move DynamicColumn dynamictableColumns = new DynamicColumn(); into your loop:

IList<DynamicColumn> idynamicttableColumns = new List<DynamicColumn>();
int count = attributeresult.Count();

for (int i = 0; i < count; i++)
{
    var item = attributeresult.ElementAt(i);
    DynamicColumn dynamictableColumns = new DynamicColumn();
    dynamictableColumns.Name = item .AttributeName;
    dynamictableColumns.Type = item .AttributeSqlType;
    dynamictableColumns.IsNullable = false;
    idynamicttableColumns.Add(dynamictableColumns);
}
