我有以下代码片段
Addresses addresses = new Addresses();
AddressInfo addr = addresses.GetAddressFromID(csTestSecurityToken, addrID);
addr.AddressCode = "SLGTest";
if (addr.AddressCode != "SLGTest")
throw new Exception("Address code did not match");
if语句总是评估为true并抛出异常，即使它显然是错误的。
有人能说清楚为什么会这样吗？
编辑：
此代码可以正常使用
Addresses addresses = new Addresses();
AddressInfo addr = addresses.GetAddressFromID(csTestSecurityToken, addrID);
addr.AddressCode = "SLGTest";
if (addr.AddressCode != "SLGTest")
throw new Exception("Address code did not match");
addr = addr;
我猜它太快处理我的物体了？

破碎的代码：
private void TestAddresses()
{
int addrID = 39294;
Addresses addresses = new Addresses();
AddressInfo addr = addresses.GetAddressFromID(csTestSecurityToken, addrID);
addr.AddressCode = "Test";
if (addr.AddressCode != "Test")
throw new Exception("Address code did not match");
try
{
// Try with SNC's security token. Should error
addr = addresses.GetAddressFromID("0AABEE33-8618-4EBA-B07A-5D6C8FFABA11", addrID);
throw new Exception("Invalid resellerid did not throw correctly.");
}
catch (Exception ex)
{
if (ex.Message != "The ResellerID for this address does not match the SecurityToken ResellerID.")
throw ex;
}
addr = addresses.GetAddressFromAddressCode(csTestSecurityToken, "SLGTest");
if (addr.AddressCode != "SLGTest")
throw new Exception("Address code did not match");
addr.Address1 = "16 North";
addr.City = "Highland";
addr.State = "UT";
addr.Zip = "84004";
addresses.UpdateAddress(csTestSecurityToken, addr);
addresses.DeleteAddress(csTestSecurityToken, addr.ID);
}
这两项工作
Addresses addresses = new Addresses();
AddressInfo addr = addresses.GetAddressFromID(csTestSecurityToken, addrID);
addr.AddressCode = "Test";
if (addr.AddressCode != "Test")
addrID = 0; // <--------------------- Changed this
try
{
// Try with SNC's security token. Should error
addr = addresses.GetAddressFromID("0AABEE33-8618-4EBA-B07A-5D6C8FFABA11", addrID);
throw new Exception("Invalid resellerid did not throw correctly.");
}
catch (Exception ex)
{
if (ex.Message != "The ResellerID for this address does not match the SecurityToken ResellerID.")
throw ex;
}
-----------------------------------------------------------
Addresses addresses = new Addresses();
AddressInfo addr = addresses.GetAddressFromID(csTestSecurityToken, addrID);
addr.AddressCode = "Test";
if (addr.AddressCode != "Test")
throw new Exception("Address code did not match");
//try
//{

试试这段代码：
public class AddrTest
{
public string AddressCode { get; set; }
}
public class Test
{
public void ThrowFail()
{
int x = 0;
AddrTest addrTest = new AddrTest();
addrTest.AddressCode = "Test";
if (addrTest.AddressCode != "Test")
throw new Exception("This shouldn't be executed.");
try
{
x = 1;
}
catch { }
}
}

您正在比较实例。尝试使用.Equals。
e.g。
if (!addr.AddressCode.Equals("SLGTest"))
throw new Exception("Address code did not match");

以某种方式似乎是IIS的问题。如果我在控制台应用程序中运行代码，它将完全按预期工作。如果我创建一个在Visual Studio Dev Web Server上运行的Web App项目，它可以正常工作。一旦切换到IIS并创建虚拟目录，它就会失败。我可以在这段代码中重新创建它。我仍然不确定原因，但添加GC.KeepAlive（）可以解决问题。
