The first method:Create a class that declares the fields that are used to store the received. It is stored in the field when it is used, and is called directly by the class name. (This method of passing is bidirectional)The second method:1. Defined in Form1public string Name = "* * * *"2. Create the Form1 object in the Form2,Form1 f = new Form1 ();And then you can go through F. Name is value.The third method: Use the constructor functionIn the form Form2int value1;String value2;Public Form2 (int

Php export csv format data implementation:First define a string storage content, such$ Exportdata = 'Rule 111, Rule 222, audit 222, Rule 222, server 2222, rule 1, rule 2, rule 3, matching character, set time, valid time '. "\ n "; Then perform a foreach loop on the array to save the csv, for example Copy codeThe Code is as follows:If (! Empty ($ lists )){Foreach

Call_user_func function is used only when the function needs to be called dynamically. This function has two usage methods:The first is to call a lonely function:Copy codeThe Code is as follows: Function funa ($ B, $ c){Echo $ B;Echo $ c;}Call_user_func ('funa', "111", "222 ");Call_user_func ('funa', "333", "444 ");// Display 111 222 333 444// Have you found that this usage is a bit like the call method in

Form1Form2 f2 = new Form2 ();F2.ShowDialog (this );// OrF2.Show (this );// OrF2.Owner = this;F2.ShowDialog (); In this way, the f2 owner is Form1. B. input values in WinFormI learned about the display of the form, and then summarized the method of passing values in the form: 1. ConstructorFeatures: it is easy to transmit values in one way (values cannot be transferred to each other ).The implementation code is as follows:In form Form2Int value1;String value2; Public Form2 (int value1, string v
