Sql server 2008 带有SQL XML插入的OutOfMemoryException

我在本地磁盘上有一个大的XML文件（150mb范围），并使用ADO.NET将其放入nvarchar（max）列中。代码如下所示（经过大量编辑，只留下代码的相关部分）：

我遇到了这个问题：

ExceptionBody:System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

   at System.IO.MemoryStream.EnsureCapacity(Int32 value)

   at System.Xml.XmlEncodedRawTextWriter.EncodeChars(Int32 startOffset, Int32 endOffset, Boolean writeAllToStream)

   at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe)
   at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()

将这种基于磁盘的大型XML放入远程DB服务器的最佳方法是什么

谢谢。

当对象没有像看到 SQL连接对象不在Using语句中，SqlCommand类也可以IDisposable

这可能不是每次内存溢出崩溃时都会出现的问题。但当内存溢出时，问题肯定会出现。

文件的大小为150mb。问题不仅在于一个文件，而且当对多个.NET任务（线程）执行此操作时，可能会有多个线程同时运行，从而耗尽CLR可用内存。谢谢。当我将大型XML文件保存到数据库中时，我首先使用二进制数据类型并对其进行压缩——令人惊讶的是，压缩文件比未压缩的XML文件小得多。在检索时，我只需解压缩XML并将其交付给客户端。如果您愿意，可以提供样品吗？您的备选方案可能是将请求排队；因此，您一次只执行几个保存。还可以跨多个服务器流式传输Xml，一次限制内存量。
