C# reflection usage method and steps

//1. Define the window class name: (The string name of the window class requires a full path name, otherwise the TYPE cannot be obtained)string customClassName = @"." + ;
 
//2. Get the string customClassName (the string name of a window class) The specified class TypeType customClassType = (customClassName);
                
//3. Generate an instance of the specified Type, equivalent to the new classobject customClassObj = (customClassType);
            
// 4. Operate on the newly generated class. This example assigns the new window to a window variablepanelForm = customClassObj as Form;
 
// This achieves the use of the string name of the class to generate an instance of the class for use by subsequent programs.

//Use and steps of reflection function: The following example is to generate an instance of the string class name and assign values ​​to the attributes or fields of the class. 
// 1. Define the class name: (The string name of the class is required, the full path name is required, otherwise the TYPE cannot be obtained)string customVaribleName = @"";
 
// 2. Get the Type of the specified class in customVaribleNameType customVaribleType = (customVaribleName);
 
// 3. Generate an instance of the specified Type, equivalent to the new classobject customAaribleObj = (customVaribleType);
 
// 4. Get the field of this class. In this example, assign a value to a common form variable, and this variable is a field here// If you assign values ​​to the attributes of this class, you need to use PropertyInfo pi = ("v" + )// In this class, is a domain a property or a field?  My personal judgment is that if the GET and SET methods are provided in this field, it is a property, otherwise it is a field, and I don’t know if it is correct?FieldInfo pi = ("v" + );
 
// 5. Assign a value to this field. This field is a window class variable. customClassObj is the window class generated based on the string in Example 1.(customAaribleObj, customClassObj);
 
// By the above5Steps，Completed according to the name of the string，Assign values ​​to fields of the corresponding class

// 1. Define the class name: (The string name of the class is required, the full path name is required, otherwise the TYPE cannot be obtained)string customVaribleName = @"";
 
// 2. Get the Type of the specified class in customVaribleNameType customVaribleType = (customVaribleName);
 
// 3. Generate an instance of the specified Type, equivalent to the new classobject customAaribleObj = (customVaribleType);
 
// 4. Get the field of this class. In this example, assign a value to a common form variable, and this variable is a field here// If you assign values ​​to the attributes of this class, you need to use PropertyInfo pi = ("v" + )// In this class, is a domain a property or a field?  My personal judgment is that if the GET and SET methods are provided in this field, it is a property, otherwise it is a field, and I don’t know if it is correct?FieldInfo pi = ("v" + );
 
// 5. Read the value of this field (in this example, the field value is a form, read the form variable, and destroy the form)((customAaribleObj) as Form).Dispose();
 
// 6. Assign a null value to this field again(customAaribleObj, null);

// The original code segment replaced by Example 3 (close the corresponding window according to the value and assign a value to the common variable)switch ()
