c# – CA2000：Microsoft.Reliability：在对所有引用超出范围之前调用System.IDisposable.Dispose对象’dt’

当我运行代码分析工具时,我得到以下内容：

Warning 1 CA2000 : Microsoft.Reliability : In method ‘Class1.test.testMethod()’,object ‘dt’ is not disposed along all exception paths. Call System.Idisposable.dispose on object ‘dt’ before all references to it are out of scope.
How to resolve the warnings??

public void testMethod()
{
   DataTable dt = new DataTable();
   DataTable dt1= new DataTable();
      try
      {
         if (dt.Rows.Count == 0)
         {
            dt1.Merge(dt);
         }
      }
      catch
      {
         throw;
      }
      finally
      {
         if (dt != null) dt.dispose();
         if (dt1 != null) dt1.dispose();
      }
}

解决方法

不确定为什么会收到该错误,但您可以在方法中尝试 using语句块并查看错误是否消失.试试吧：

public void testMethod()
{
    using (DataTable dt = new DataTable())
    using (DataView dv = new DataView(dt))
    {
        //your work
    }
}
