Set and Return System Variables
设置和返回系统变量

The Application object provides the SetSystemVariable and GetSystemVariable methods for setting and retrieving AutoCAD system variables. For example, to assign an integer to the MAXSORT system variable, use the following code:

Application对象提供了SetSystemVariable方法和GetSystemVariable方法来设置和提取系统变量。例如，下例代码将一个整数赋值给系统变量MAXSORT：

VB.NET

'' Get the current value from a system variable

Dim nMaxSort as Integer = Application.GetSystemVariable("MAXSORT")

'' Set system variable to new value

Application.SetSystemVariable("MAXSORT", 100)

C#

// Get the current value from a system variable取值

int nMaxSort = System.Convert.ToInt32(Application.GetSystemVariable("MAXSORT"));

// Set system variable to new value赋值

Application.SetSystemVariable("MAXSORT", 100);

VBA/ActiveX Code Reference

'' Get the current value from a system variable

Dim nMaxSort as Integer

nMaxSort = ThisDrawing.GetVariable("MAXSORT")

'' Set system variable to new value

ThisDrawing.SetVariable "MAXSORT", 100
