【问题描述】：
我正在使用 C# 导出到 Excel，但在某些记录上出现此错误。
The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data
通过谷歌搜索，我发现它与大小限制有关，但我找不到解决方法。有什么想法吗？
请求的代码：
string lFilename = Leads.xls";
string lDistributorFolder = Server.MapPath(".") + "\\Portals\\0\\Distributors\\" + _currentUser.UserID.ToString() + "\\";
string lTemplateFolder = System.Configuration.ConfigurationManager.AppSettings["Templates"];
System.IO.Directory.CreateDirectory(lDistributorFolder);
File.Copy(lTemplateFolder + lFilename, lDistributorFolder + lFilename, true);
string lConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + lDistributorFolder + "\\" + lFilename + ";Extended Properties=\"Excel 8.0;HDR=YES;\"";
DbProviderFactory lFactory = DbProviderFactories.GetFactory("System.Data.OleDb");
int lSequence = 0;
using (DbConnection lConnection = lFactory.CreateConnection())
{
lConnection.ConnectionString = lConnectionString;
lConnection.Open();
foreach (GridDataItem lItem in grdLeadList.Items)
{
lSequence++;
using (DbCommand lCommand = lConnection.CreateCommand())
{
lCommand.CommandText = "INSERT INTO [ColderLeads$] ";
lCommand.CommandText += "(F1,F2,F3,F4,F5,F6,F7,F8,F9,F10,F11,F12,F13,F14,F15,F16,F17,F18,F19,F20,F21) ";
lCommand.CommandText += "VALUES(";
lCommand.CommandText += "\"" + lSequence.ToString() + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gLeadNumber].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gSource].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gAccountName].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gCreatedOn].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gContactFullName].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gPriority].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gStreet1].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gStreet2].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gZIP].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gCity].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += "\"" + lItem.Cells[_gState].Text.Replace(" ", " ") + "\",";
lCommand.CommandText += ")";
lCommand.ExecuteNonQuery();
}
}
lConnection.Close();
}
谢谢！
【问题讨论】：
-
你能展示你用来导出的代码，以及它失败的数据元素吗？
-
I am exporting to Excel using C#- 您忘记在问题中显示 C#。 -
@M.Babcock，无法解释的否决票？前两个 cmets 有什么不清楚的地方吗？你还需要什么解释？附：我没有投反对票，但完全同意投反对票的人。这就像对机械师说：我的车坏了，问他为什么不带车。更糟糕的是：你让他修理你的车而不带坏车（我想 OP 是在要求我们修复他的代码）。
-
@M.Babcock：由于前两个 cmets 中所述的原因，我投了反对票；因此，为什么我赞成第一条评论。一旦贾斯汀添加了必要的信息，我肯定会删除我的反对票。
-
@DarinDimitrov - Justin 没有要求我们修复他的代码（对于大多数值得被否决的人来说，这比我能说的要多），他询问如何解决一个常见错误。他最初的问题更类似于，我的车不会启动，因为发动机不会转动。有足够的信息来理论化解决方案。
