问题 CA2000 is a warning regarding the IDisposable interface: CA2000 : Microsoft.Reliability : In method 'ImportProcessor.GetContext(string)', call System.IDisposable.Dispose on object 'c' before all references to it are out of scope. My method is used to store a cache of context like so: public class RegionContext : IDisposable { /* Implement Dispose() here */ } private Dictionary<string, RegionContext> contextCache = new ..... (); public RegionContext GetContext(string regionCode) {

问题 I have a function which I thought I had fixed the CA2000 warning in Code Analysis for, but it just won't go away. The warning is on SqlCommand. Here's the function: protected internal void LogUserSession(int? managerID) { using (var sqlCommand = new SqlCommand()) { sqlCommand.SetCommand("usp_UserActivity_Create"); SqlParameter prmSessionID = new SqlParameter(); prmSessionID.ParameterName = "@sessionID"; prmSessionID.Direction = ParameterDirection.Input; prmSessionID.SqlDbType = SqlDbType

问题 I have lots of code like this: FileStream fs = File.Open(@"C:\Temp\SNB-RSS.xml", FileMode.Open); using (XmlTextReader reader = new XmlTextReader(fs)) { /* Some other code */ } This gives me the following Code Analysis warning: CA2000 : Microsoft.Reliability : In method 'SF_Tester.Run()', object 'fs' is not disposed along all exception paths. Call System.IDisposable.Dispose on object 'fs' before all references to it are out of scope. If I follow the suggestion and I put the File.Open in a

问题 I am using DataVisualization.Charting.Chart extensively, and for the most part it is working. However, I've been running Code Analysis frequently, and have all my own warnings taken care of. But, there are about 30 CA2000 (object not disposed along all exception paths) in the *.Designer.cs files that use the charting. The Designer files are generating pretty much all the charting code, and almost all the charting elements implement IDisposable . I have "Suppress results from generated code"

CA2000 passing object reference to base constructor in C#

I receive a warning when I run some code through Visual Studio's Code Analysis utility which I'm not sure how to resolve. Perhaps someone here has come across a similar issue, resolved it, and is willing to share their insight. I'm programming a custom-painted cell used in a DataGridView control. The code resembles: public class DataGridViewMyCustomColumn : DataGridViewColumn { public DataGridViewMyCustomColumn() : base(new DataGridViewMyCustomCell()) { } It generates the following warning: CA2000 : Microsoft.Reliability : In method 'DataGridViewMyCustomColumn.DataGridViewMyCustomColumn()'
