一丶webservice执行存储过程

返回值组合：

json返回

1 StringBuilder sb = new StringBuilder();
2 sb.Append("{");
3 sb.Append("\"Status\":\"" + 123 + "\"");
4 sb.Append("}");

json数组

StringBuilder sb = new StringBuilder();
sb.Append("[");
for (int i = 0; i < 10; i++)
{
     sb.Append("{");
     sb.Append("\"name\":\"" + i + "\",");
     sb.Append("\"name1\":\"" + (i+1) + "\"");
     sb.Append("},");
}
sb.Remove(sb.ToString().LastIndexOf(','), 1);
sb.Append("]");
