C# thread pool limiting threads
Note: if you are limiting this to “3” just so you don’t overwhelm the machine running your app, I’d make sure this is a problem first. The threadpool is supposed to manage this for you. On the other hand, if you don’t want to overwhelm some other resource, then read on! You can’t manage the … Read more
Create List with values at compile time
List<int> myValues = new List<int>(new int[] { 1, 2, 3 } ); This will create an intermediate array however so there may be a more efficient way of doing the same thing. EDIT: John Feminella suggested creating a factory method to accept a list of parameters and return a List which you could implement as … Read more
Speed up File.Exists for non existing network shares
In a nutshell Build a list of available drives. Try to resolve the driveletter to an UNC name. Try to ping the drive. Edit regarding Bill’s comment if Google is not the referer, EE doesn’t show the answer for free. Links to EE are not helpful. OP found the article I’ve mentioned in my original … Read more
C#: multiline text in DataGridView control
You should set DefaultCellStyle.WrapMode property of column to DataGridViewTriState.True. After that text in cells will be displayed correctly. Example (DataGridView with one column): dataGridView1.Columns[0].DefaultCellStyle.WrapMode = DataGridViewTriState.True; dataGridView1.Rows.Add(“test” + Environment.NewLine + “test”); (Environment.NewLine = \r\n in Windows)
Why shouldn’t I always use nullable types in C#
The reason why you shouldn’t always use nullable types is that sometimes you’re able to guarantee that a value will be initialized. And you should try to design your code so that this is the case as often as possible. If there is no way a value can possibly be uninitialized, then there is no … Read more
Test events with nunit
Checking if events were fired can be done by subscribing to that event and setting a boolean value: var wasCalled = false; foo.NyEvent += (o,e) => wasCalled = true; … Assert.IsTrue(wasCalled); Due to request – without lambdas: var wasCalled = false; foo.NyEvent += delegate(o,e){ wasCalled = true;} … Assert.IsTrue(wasCalled);
static readonly field initializer vs static constructor initialization
There is one subtle difference between these two, which can be seen in the IL code – putting an explicit static constructor tells the C# compiler not to mark the type as beforefieldinit. The beforefieldinit affects when the type initializer is run and knowing about this is useful when writing lazy singletons in C#, for … Read more
End of Stream encountered before parsing was completed?
Try to set the position to 0 of your stream and do not use your object but the object type. BinaryFormatter b = new BinaryFormatter(); s.Position = 0; return (YourObjectType)b.Deserialize(s);
How to use LogonUser properly to impersonate domain user from workgroup client
Very few posts suggest using LOGON_TYPE_NEW_CREDENTIALS instead of LOGON_TYPE_NETWORK or LOGON_TYPE_INTERACTIVE. I had an impersonation issue with one machine connected to a domain and one not, and this fixed it. The last code snippet in this post suggests that impersonating across a forest does work, but it doesn’t specifically say anything about trust being set … Read more
