对象引用丢失，但保留的资源被保留 [英] Object references are lost but the resources held are retained

问题描述

IndentedTextWriter tw = new IndentedTextWriter(internalTW, "    ");

"tw"引用的对象丢失，但此处未配置相关资源."TW"是文本编写器，其中internalTW是TextWriter

Object referenced by 'tw' is lost, but related resources are not disposed here "TW " is a text writer where internalTW is a TextWriter

 OleDbConnection con = new OleDbConnection(conStr);
 OleDbCommand cmd = new OleDbCommand(cmd1, con);

'cmd'引用的对象丢失，但此处未配置相关资源

object referenced by 'cmd' is lost, but related resources are not disposed here

推荐答案

尝试

using (IndentedTextWriter tw = new IndentedTextWriter(internalTW, "    ")) {
  // use it here
}

resp.

using (OleDbConnection con = new OleDbConnection(conStr))
using (OleDbCommand cmd = new OleDbCommand(cmd1, con)) {
  // use it here
}

在 using 块的末尾，在对象上调用 Dispose()，并且应该释放资源...

At the end of the using block, Dispose() is called on the objects and the resources should be freed...
