c# - 使用 C# 代码格式化完整地址

Question

我已经编写了以下代码行来格式化地址

         string Address1 = ds.Tables[0].Rows[0]["PhysicalAddressLine1"].ToString();
            string Address2 = ds.Tables[0].Rows[0]["PhysicalAddressLine2"].ToString();
            string Address1C;
            string Address2C;

            if (Address1 != "")
                Address1C = Address1 + ", ";
            else
                Address1C = Address1;

            if (Address2 != "")
                Address2C = Address2 + ", ";
            else
                Address2C = Address2;



            lblAdderssX1.Text = Address1C + Address2C;

            string City = ds.Tables[0].Rows[0]["PhysicalAddressCity"].ToString();
            string CityC;
            if (City != "")
                CityC = City + ", ";
            else
                CityC = City;

            string Pin = ds.Tables[0].Rows[0]["PhysicalAddressPin"].ToString();

            string State = ds.Tables[0].Rows[0]["JurisdictionX"].ToString();
            string StateC;

            if (State != "")
                StateC = State + ", ";
            else
                StateC = State;

          //  string CountryC = ds.Tables[0].Rows[0]["CountryX"].ToString();

            lblAddressX2.Text = CityC + StateC + Pin;

         "<asp:Label ID="lblAdderssX1" CssClass="ProfileLabel" runat="server"> </asp:Label>
                                                                                   <asp:Label ID="lblAddressX2" CssClass="ProfileLabel" runat="server"> </asp:Label>"

其实我们希望格式应该是这样的

“物理地址 1、物理地址 2、城市、州、密码”

如果缺少其中任何一个，假设物理地址 2 那么地址应该是

“实际地址 1、城市、州、密码”

如果表格中缺少城市，那么它应该是这样的

“物理地址 1、物理地址 2、状态、密码”

如果 Physical Address2、City、State、Pin 丢失，那么地址应该是这样的

“Physical Address1”，目前上面是 placing ，在这种情况下。我无法处理这个。请帮忙!!!

此外，如果没有可用的文本，则文本应显示为“不可用”

我想你想把它写得更干净。创建List<string>

List<string> address = new List<string>();
address.Add(ds.Tables[0].Rows[0]["PhysicalAddressLine1"].ToString());
address.Add(ds.Tables[0].Rows[0]["PhysicalAddressLine2"].ToString());
address.Add(ds.Tables[0].Rows[0]["PhysicalAddressCity"].ToString());
address.Add(ds.Tables[0].Rows[0]["JurisdictionX"].ToString());
address.Add(ds.Tables[0].Rows[0]["PhysicalAddressPin"].ToString());

string list = string.Join(", ", address.Where(x => !string.IsNullOrEmpty(x)));
