Reason:At the time of the loop, when the collection has been deleted, the total count and index will change. So it's going to get an error.Workaround:Do not perform an action on the list that enumerates the collection (for example, foreach) to perform an operation that modifies the collection. If you need to modify the collection, first use the ToArray () method to convert to an array, for exampleforeach(string s in rs.ToArray()) { if(s.IndexOf(t)C # Workaround for "the collection modifie

When using. NET development, it is very convenient for you to return the query results as a datatable, but it is very troublesome to retrieve data and there is no convenient model type retrieval. Therefore, many people do this in the following ways: // Obtain the query resultDatatable dt = dbhelper. executedatatable (...);// Convert datatable to ilist Ilist Q: If the system has dozens or even hundreds of models, isn't every model having to write a method to convert datatable to this model?Solut

Generally, we use entity classes in generic projects. However, when we process special data, we must not convert the generics into datatable, The following is a common method, which is implemented through reflection... /// /// Convert the List class of the generic set to datatable/// /// /// Public static datatable listtodatatable {// Check whether the object set cannot be emptyIf (entitys = NULL | entitys. Count {Throw new exception ("the set to be converted is empty ");}// Retrieve all proper

Dataset objects support ADO. the core object of the net disconnected and distributed data solution, which is widely used. we often need to use the data, such as getting data from a able, copying data from another Abe, or data from datarow. However, only the replication of dataset and datatable supports deep replication, that is to say, the structure of the element can be copied, and the data of the element can be copied. The datatdatarow has no releva

Converts a able object to A recordset object. In. net, ADO. NET is used to replace ADO for data access. However, some COM controls only support ADO and do not support ADO. net. To use this type of control, only data objects in ADO. Net can be used. For example, datatable Is A recordset In ADO (the DataSet object is essentially a set of datatable, so this article only describes datatable object conversion ).Ideas1. After creating A recordset object, cr
