如果我使用 GUID,Membership.GetUser问题 可以正常工作,但如果我在没有参数或名称的情况下尝试它会失败:
//This works and adds records to aspnet_user & aspnet_Membership tables
MembershipUser membershipUser = Membership.CreateUser(_name, _pwd, _email, null, null, true, null, out createStatus);
//These fail with an InvalidCastException
MembershipUser membershipUser2 = Membership.GetUser(_name, true);
MembershipUser membershipUser3 = Membership.GetUser();
//If I go look up the GUID for this user (userId), this works!
MembershipUser membershipUser4 = Membership.GetUser(new Guid("E1428CD3-CF17-494E-AB77-CF8F6010F585"), true);
其他谜团
//This works
Int32 count = Membership.GetNumberOfUsersOnline();
//this fails (but totalRecords has the right value)
Int32 totalRecords;
MembershipUserCollection col = Membership.GetAllUsers(0,100, out totalRecords);
设置
- MVC
- .NET 4.0
- 默认 SQL 成员资格提供程序(无自定义或覆盖)
前任:
<membership defaultProvider="SqlProvider">
<providers>
<clear />
<add name="SqlProvider"
type="System.Web.Security.SqlMembershipProvider"
connectionStringName="MyDB"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="false"
applicationName="myapp"
requiresUniqueEmail="false"
passwordFormat="Hashed"
maxInvalidPasswordAttempts="5"
minRequiredPasswordLength="2"
minRequiredNonalphanumericCharacters="0"
passwordAttemptWindow="10"
passwordStrengthRegularExpression="" />
</providers>
</membership>
- 没有自定义或额外键的标准 aspnet_* 数据库表
- aspnet_Membership_GetAllUsers 从数据库手动运行良好。重定向输出显示正在返回预期结果
- aspnet_Membership_GetUserByName 在数据库中也可以正常工作

Specified cast is not valid.
at System.Data.SqlClient.SqlBuffer.get_SqlGuid()

at System.Web.Security.SqlMembershipProvider.GetUser(String username, Boolean userIsOnline)
at System.Web.Security.Membership.GetUser(String username, Boolean userIsOnline)
想法
几乎就像 Membership.GetUser 方法内部有问题。我为我的 System.Web.dll(4.0 版)反映了 System.Web.Security.SqlMembershipProvider.GetUser 的代码,我得到以下信息:
public override MembershipUser GetUser(string username, bool userIsOnline)
{
SecUtility.CheckParameter(ref username, true, false, true, 256, "username");
SqlDataReader reader = (SqlDataReader) null;
try
{
SqlConnectionHolder connectionHolder = (SqlConnectionHolder) null;
try
{
connectionHolder = SqlConnectionHelper.GetConnection(this._sqlConnectionString, true);
this.CheckSchemaVersion(connectionHolder.Connection);
SqlCommand sqlCommand = new SqlCommand("dbo.aspnet_Membership_GetUserByName", connectionHolder.Connection);
sqlCommand.CommandTimeout = this.CommandTimeout;
sqlCommand.CommandType = CommandType.StoredProcedure;
sqlCommand.Parameters.Add(this.CreateInputParam("@ApplicationName", SqlDbType.NVarChar, (object) this.ApplicationName));
sqlCommand.Parameters.Add(this.CreateInputParam("@UserName", SqlDbType.NVarChar, (object) username));
sqlCommand.Parameters.Add(this.CreateInputParam("@UpdateLastActivity", SqlDbType.Bit, (object) (bool) (userIsOnline ? 1 : 0)));
sqlCommand.Parameters.Add(this.CreateInputParam("@CurrentTimeUtc", SqlDbType.DateTime, (object) DateTime.UtcNow));
SqlParameter sqlParameter = new SqlParameter("@ReturnValue", SqlDbType.Int);
sqlParameter.Direction = ParameterDirection.ReturnValue;
sqlCommand.Parameters.Add(sqlParameter);
reader = sqlCommand.ExecuteReader();
if (!reader.Read())
return (MembershipUser) null;
string nullableString1 = this.GetNullableString(reader, 0);
string nullableString2 = this.GetNullableString(reader, 1);
string nullableString3 = this.GetNullableString(reader, 2);
bool boolean1 = reader.GetBoolean(3);
DateTime creationDate = reader.GetDateTime(4).ToLocalTime();
DateTime lastLoginDate = reader.GetDateTime(5).ToLocalTime();
DateTime lastActivityDate = reader.GetDateTime(6).ToLocalTime();
DateTime lastPasswordChangedDate = reader.GetDateTime(7).ToLocalTime();
Guid guid = reader.GetGuid(8);
bool boolean2 = reader.GetBoolean(9);
DateTime lastLockoutDate = reader.GetDateTime(10).ToLocalTime();
return new MembershipUser(this.Name, username, (object) guid, nullableString1, nullableString2, nullableString3, boolean1, boolean2, creationDate, lastLoginDate, lastActivityDate, lastPasswordChangedDate, lastLockoutDate);
}
finally
{
if (reader != null)
reader.Close();
if (connectionHolder != null)
connectionHolder.Close();
}
}
catch
{
throw;
}
}
下一步
我希望从 SO 人群中得到一些关于我下一步应该去哪里的方向。我想我可以重写这个方法并将我自己的提供程序放在一起只是为了调试它,或者我可以绕过该死的东西并自己直接调用数据库。这似乎是一些基本的 DB CRUD 带来的很多心痛。
当前状态
- 2013 年 3 月 5 日:我今天早上发现我的
aspnet_Users
桌子上有UserId
as annvarchar(256)
而不是uniqueidentifier
. 也许SqlDataReader.GetGuid()
那里窒息。今晚我会进行一些测试,看看是否是问题所在。我想知道我的表结构是否已过时,因为在线文档将此字段显示为uniqueidentifier
.
