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>"

实际上我们希望格式应该像

"Physical Address1, Physical Address2, City, State, Pin"

如果缺少其中任何一个，假设物理地址 2 那么地址应该是

"Physical Address1, City, State, Pin"

如果 table 中缺少城市，那么它应该像

"Physical Address1, Physical Address2, State, Pin"

如果缺少物理地址 2、城市、州、密码，则地址应类似于

"Physical Address1" 并且当前上面是 placing ，在这种情况下。我无法处理这个。请帮助!!!

此外，如果没有可用的文本，那么文本应该像 "Not Available"

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)));

字符串地址 1 = ds.Tables[0].行[0]["PhysicalAddressLine1"].ToString();

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

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

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

        string Address1C;

        if(!string.IsNullOrEmpty(Address1))
            Address1C=Address1;

        if (!string.IsNullOrEmpty(Address2))
        {
            if (!string.IsNullOrEmpty(Address1C))
                Address1C = ", "+ Address2 ;
            else
            Address1C=Address2;
        }
        if (!string.IsNullOrEmpty(City))
        {
            if (!string.IsNullOrEmpty(Address1C))
                Address1C = ", "+ City ;
            else
            Address1C=City;
        }

        if (!string.IsNullOrEmpty(State))
        {
            if (!string.IsNullOrEmpty(Address1C))
                Address1C = ", "+ State ;
            else
            Address1C=State;
        }
    if (!string.IsNullOrEmpty(Pin))
        {
            if (!string.IsNullOrEmpty(Address1C))
                Address1C = ", "+ Pin ;
            else
            Address1C=Pin;
        }
        if(!string.IsNullOrEmpty(Address1C))
            lblAdderssX1.Text = Address1C;
        else
        lblAdderssX1.Text = "Not Available";            


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

试试这个，

string address = string.Empty;

if ((ds.Tables[0].Rows[0]["PhysicalAddressLine1"] != null) && !string.IsNullOrEmpty(ds.Tables[0].Rows[0]["PhysicalAddressLine1"].ToString()))
    address += ds.Tables[0].Rows[0]["PhysicalAddressLine1"].ToString() + ", ";

if ((ds.Tables[0].Rows[0]["PhysicalAddressLine2"] != null) && !string.IsNullOrEmpty(ds.Tables[0].Rows[0]["PhysicalAddressLine2"].ToString()))
    address += ds.Tables[0].Rows[0]["PhysicalAddressLine2"].ToString() + ", ";

if ((ds.Tables[0].Rows[0]["PhysicalAddressCity"] != null) && !string.IsNullOrEmpty(ds.Tables[0].Rows[0]["PhysicalAddressCity"].ToString()))
    address += ds.Tables[0].Rows[0]["PhysicalAddressCity"].ToString() + ", ";

if ((ds.Tables[0].Rows[0]["JurisdictionX"] != null) && !string.IsNullOrEmpty(ds.Tables[0].Rows[0]["JurisdictionX"].ToString()))
    address += ds.Tables[0].Rows[0]["JurisdictionX"].ToString() + ", ";

if ((ds.Tables[0].Rows[0]["PhysicalAddressPin"] != null) && !string.IsNullOrEmpty(ds.Tables[0].Rows[0]["PhysicalAddressPin"].ToString()))
    address += ds.Tables[0].Rows[0]["PhysicalAddressPin"].ToString() + ", ";

address = address.TrimEnd(", ");
