【中文标题】插入数组列表时，索引（从零开始）必须大于或等于零且小于参数列表的大小【英文标题】：Index (zero based) must be greater than or equal to zero and less than the size of the argument list while inserting the arraylist 【发布时间】：2014-12-22 07:40:21 【问题描述】：我收到此错误：
索引（从零开始）必须大于或等于零且小于参数列表的大小。
在这里：
splitItems = item.Split(",".ToCharArray());
sb.AppendFormat("0('1','2','3','4'); ",
ds.InsertPlan("1", splitItems[0], splitItems[1], splitItems[2],
splitItems[3], DateTime.Now, DateTime.Now, user, user, "Nil", 1));

【问题讨论】：
看起来问题出在从 splitItems araay 中获取项目。您能否在使用 splitItems[3] 时检查您的 splitItems 数组是否包含 4 个项目？item 的值是多少？
@jadavparesh06 是的，我签入了，我可以看到里面有 4 个项目..
@GrantWinney 项目的值是日期、地点 1、地点 2、距离。
吉鲁我删除了aspx代码以简化其他读者的问题。
【参考方案1】：
您的 sb.AppendFormat 格式字符串需要 5 项。
您说 ds.InsertPlan() 具有以下签名，并且 参数映射到 InsertPlan() 而不是 AppendFormat()。但是，InsertPlan() 返回一个 int，所以 AppendFormat() 只有一个参数，一个 int 值。
public virtual int InsertPlan(
string Plan_ID, <- "1"
string Place_1, <- splitItems[0]
string Place_2, <- splitItems[1]
string Distance, <- splitItems[2]
string Date, <- splitItems[3]
System.Nullable<System.DateTime> Created_Time, <- DateTime.Now
System.Nullable<System.DateTime> Updated_Time, <- DateTime.Now
string Created_by, <- user
string Updated_By, <- user
string Version_Status, <- "Nil"
System.Nullable<int> p3 <- 1
)
您的代码：
sb.AppendFormat("0('1','2','3','4'); ",
ds.InsertPlan("1", // <-- unless InsertPlan() returns an array, then this
// is only 1 argument to the outer function
splitItems[0],
splitItems[1],
splitItems[2],
splitItems[3],
DateTime.Now, DateTime.Now, user, user, "Nil", 1
)
);
就像：
sb.AppendFormat("0('1','2','3','4'); ",
1); // only 0 has a argument
// 1 ... 4 do not
【讨论】：
我检查了一下，我看到 splititem 中有 4 个项目。 是的，我看错了。它是关于 AppendFormat() 格式字符串，而不是数组。我修改了。 ds.InsertPlan 是一个数据集。我希望将这些值插入数据库中......任何替代方案。 您的代码调用了 2 个函数，sb.AppendFormat 和 ds.InsertPlan。也许您应该先调用一个，而不是在参数列表中。 查看我的编辑。您的参数都将转到 InsertPlan，它返回一个整数。为什么要将单个整数传递给 AppendFormat() ？你想附加什么？以上是关于插入数组列表时，索引（从零开始）必须大于或等于零且小于参数列表的大小的主要内容，如果未能解决你的问题，请参考以下文章
