c#中的通用参数

Question

我有这个课程:

interface Info{}

class AInfo : Info { }
class BInfo : Info { }

class SendInfo {
    static public f_WriteInfo(params Info[] _info) {

    }
}

class Test {
  static void Main() {
    SendInfo.f_WriteInfo( 
                        new[] { 
                            new AInfo(){ ... },
                            new BInfo(){ ... },
                       } );
// This will generate an error. 
// There will be need casting between new and [] like new Info[]
  }
}

没有铸造有没有办法做到这一点？

喜欢:

class SendInfo {
    static public f_WriteInfo(params T _info) where T : Info {

Answer 1

将方法签名设置为:

static public f_WriteInfo(params Info[] _info) {}

并称之为:

SendInfo.f_WriteInfo(new AInfo(){ ... }, new BInfo(){ ... });
