问题 By monitoring the CLR #Bytes in all Heaps performance counter of a brand new .NET 4.5 server application over the last few days, I can notice a pattern that makes me think that Gen2 collection is not always collecting dead objects, but I am having trouble understanding what exactly is going on.

问题 I have read several posts on this online, but none of them have resolved my issue. Most of the questions posted online point me towards checking Dbnull values from the database and I am doing that in the code. Here's the code where the exception is thrown: int rowNum = Convert.ToInt32(dataTable.Rows[r][dataTable.Columns.Count - 2]); Here's the code where I am checking for the dbnull values: for (int r = 0; r < dataTable.Rows.Count - 1; r++) //rows { for (int c = 1; c < dataTable.Columns.Count

问题 So I've made a form where you login from a DB. Code should be self explanatory. private void button1_Click(object sender, EventArgs e) { try { string MyConnection = "datasource=localhost;port=3306;username=root;password=xdmemes123"; MySqlConnection myConn = new MySqlConnection(MyConnection); MySqlCommand SelectCommand = new MySqlCommand("select * from life.players where DBname='" + this.username.Text + "' and DBpass='" + this.password.Text +"' ; ", myConn); MySqlDataReader myReader; myConn

问题 What I can't understand fully is exemplified in a unit test below. Basically I want to know why DbContext overrides collection values currently stored in the database even if Reload() and a new load for the collection has been called. If I try to call dbContext.Entry(test.TestChildren).Reload(); I get the exception: System.InvalidOperationException: 'The entity type 'List' was not found. Ensure that the entity type has been added to the model.' I have also loaded TestChildren explicitly via

问题 I need to broaden my understanding of how structs are compiled when using generics. I have the following code, which works public struct TestStruct { public GenericStruct<SecondTestStruct> Header; public int TestValue; } public struct GenericStruct<T> { public int MessageSize => System.Runtime.InteropServices.Marshal.SizeOf(typeof(T)); } public struct SecondTestStruct { public int TestValue; } static void Main(string[] args) { TestStruct test = new TestStruct(); Console.WriteLine($"Size of
