C# 在asp.net c中将datatable转换为包含15k条记录的xml#

我在datatable中有15k条记录，无法将datatable转换为xml，从而导致asp.net c#中出现内存异常

如果.net版本允许，可以尝试使用此方法DataTable.WriteXml

DataSet ds = new DataSet();
DataTable customerTable = GetCustomers();
DataTable orderTable = GetOrders();

ds.Tables.Add(customerTable);
ds.Tables.Add(orderTable);
ds.Relations.Add("CustomerOrder",
    new DataColumn[] { customerTable.Columns[0] },
    new DataColumn[] { orderTable.Columns[1] }, true);

System.IO.StringWriter writer = new System.IO.StringWriter();
customerTable.WriteXml(writer, XmlWriteMode.WriteSchema, false);

请提供您的问题的示例代码。XmlDocument xmlDoc=new XmlDocument（）；使用（MemoryStream MemoryStream=new MemoryStream（））{using（TextWriter streamWriter=new streamWriter（MemoryStream））{XmlSerializer XmlSerializer=new XmlSerializer（typeof（DataTable））；XmlSerializer.Serialize（streamWriter，dt）；if（MemoryStream.Position>0）{memoryStream.Position=0；}xmlDoc.Load（memoryStream）；}}}这是否回答了您的问题？我缺少的代码是，它在xmlSerializer.Serialize（streamWriter，dt）上引发异常；行。正在序列化多少条记录？看起来您正试图将大量数据序列化到MemoryStream中，结果导致内存不足。如何将writer加载到xml文档中。请给出相关示例

DataSet ds = new DataSet();
DataTable customerTable = GetCustomers();
DataTable orderTable = GetOrders();

ds.Tables.Add(customerTable);
ds.Tables.Add(orderTable);
ds.Relations.Add("CustomerOrder",
    new DataColumn[] { customerTable.Columns[0] },
    new DataColumn[] { orderTable.Columns[1] }, true);

System.IO.StringWriter writer = new System.IO.StringWriter();
customerTable.WriteXml(writer, XmlWriteMode.WriteSchema, false);
