在VS2010中如何判断一个类需要被释放？
在 Visual Studio 2010 中是否有一种简单的方法可以知道类型是否需要被释放？
例如，我编写代码：
Collection<Prize> prizes = new Collection<Prize>();
我不知道是否需要调用 dispose。
我现在处理它的方式是单击Collection并按F12，寻找IDisposable：
public class Collection<T> : IList<T>, ICollection<T>, IEnumerable<T>, IList, ICollection, IEnumerable
然后我递归地深入到每个类，寻找如果有实现IDisposable：
public class Collection<T> : IList<T>, ICollection<T>, IEnumerable<T>, IList, ICollection, IEnumerable
public interface IList<T> : ICollection<T>, IEnumerable<T>, IEnumerable
public interface ICollection<T> : IEnumerable<T>, IEnumerable
public interface IEnumerable<T> : IEnumerable
public interface IEnumerable
public interface IEnumerable
public interface IEnumerable<T> : IEnumerable
public interface IEnumerable
...
注意：不要将示例与问题混淆。我可能有代码：
SqlConnection conn = new SqlConnection();然后我反复迭代祖先类型：
公共密封类 SqlConnection ：DbConnection、ICloneable 公共抽象类 DbConnection ：组件、IDbConnection、IDisposable所以我发现这个类需要我调用
Dispose。但如果我不必 F12 下降到东西中会更容易
Is there an easy way, in Visual Studio 2010, to know if a type needs to be disposed?
e.g. i write code:
Collection<Prize> prizes = new Collection<Prize>();
i don't know if i need to call dispose.
The way i handle it now is click on Collection and press F12, looking for IDisposable:
public class Collection<T> : IList<T>, ICollection<T>, IEnumerable<T>, IList, ICollection, IEnumerable
then i recursively descend into each class, looking to see if any implement IDisposable:
public class Collection<T> : IList<T>, ICollection<T>, IEnumerable<T>, IList, ICollection, IEnumerable
public interface IList<T> : ICollection<T>, IEnumerable<T>, IEnumerable
public interface ICollection<T> : IEnumerable<T>, IEnumerable
public interface IEnumerable<T> : IEnumerable
public interface IEnumerable
public interface IEnumerable
public interface IEnumerable<T> : IEnumerable
public interface IEnumerable
...
Note: Don't confuse the example with the question. i might have the code:
SqlConnection conn = new SqlConnection();where i then recusively iterate into ancestor types:
public sealed class SqlConnection : DbConnection, ICloneable public abstract class DbConnection : Component, IDbConnection, IDisposableSo i've found that this class needs me to call
Dispose. But it would be easier if i didn't have to F12 descend into stuff

如果您有高级版或终极版代码分析规则CA1001：拥有一次性字段的类型应该bedisposable 将找到需要处置的类型。要启用代码分析，请转到项目属性并选择代码分析选项卡，选择“在生成时启用代码分析”，必须包含 Microsoft.Design 规则集才能运行 CA1001 规则。
Devexpress 的 Coderush 包含类似的功能。这是标准版的唯一选项。可能还有其他提供类似功能的加载项。
这在 Express 版本中无法完成。
If you have the premium or ultimate edition code analysis rule CA1001:Types that own disposable fields should be disposable will find types that need to be disposed. To enable code analysis go to the project properties and select the code analysis tab, select Enable Code Analysis on Build, the Microsoft.Design ruleset must be included for the CA1001 rule to run.
Coderush from Devexpress includes similar functionality. This is the only option for the standard edition. There may other add-ins that offer similar functionality.
This cannot be done in the express edition.
