直接上代码，后面说应用场景
新建一个项目，引入需要调用的dll，如下
class Program
{
[DllImport( "soft.dll" )]
static extern int CreditTrans( StringBuilder strin, StringBuilder strout );
static int Main( string[] args )
{
if( args== null || args.Length < 1 )
{
return -1;
}
StringBuilder sb = new StringBuilder();
int result = CreditTrans( new StringBuilder( args[0] ), sb );
Console.WriteLine( sb.ToString() );
return result;
}
}
