C# 如何终止和启动进程

在我的c#程序（使用Visual Studio 2010）中，我正在将文件上传到SharePoint文档库，问题是我正在运行我们的内存，显然进程"sqlservr.exe * 32"就像超过一GB的内存。为了上传文件，我首先将文件的字节读取到 byte[] 数组中。然后将数组作为文件上载到文档库。我需要一种方法在上传每个文件之前清除内存。

程序在循环中上传文件，该循环在目录中迭代。那么有没有办法清除 byte[] 数组的内存呢？

实际上有没有办法重新启动进程"sqlservr.exe*32"以释放内存？

这是我用来上传的代码：

我在网站上看到的错误消息是（当问题发生时，我认为是内存不足，有时消息中的文件也不同）：网址"测试库/我的文件夹/文件.txt"无效。 它可能引用不存在的文件或文件夹，或者引用当前 Web 中不存在的有效文件或文件夹。
