String::Concat note(About array^ and array^ )

array<Byte^>^ temp1 = gcnew array<Byte^>^(10);

array<Byte >^ temp2 = gcnew array<Byte >^(10);

 

String^ LinkAllBytes = String::Concat(temp1);----------------------OK

String^ LinkAllBytes = String::Concat(temp2);----------------------NG

.Net Framework v2.0 心得－> 实体数组作为函数的输出参数时应注意的

当实体数组作为函数的输出参数时，只能在函数对内部成员进行修改，但无法改变此实体的大小。

 

如：

 

void main()

{

      array<String^>^ sample = {"Text1", "Text2"};

 

      resize (sample);

 

      printf("sample element 0 = %s\n", sample[0]);

      printf("sample element 1 = %s\n", sample[1]);

      printf("sample size external = %d\n", sample->Length);

}

void resize(array<String^>^ sample)

{

      sample[0] = "Text2";

      sample[1] = "Text1";

      Array::Resize(sample, 4);

      printf("sample size internal = %d\n\n", sample->Length);

}

 

打印：

sample size internal = 4;

 

sample element 0 = Text2;

sample element 1 = Text1;

sample size external = 2;
