我正在开展一个就业申请项目。我想将用户的文本框输入保存到多个表。我的代码在构建时没有显示警告或错误，但是当我进行调试时，它只是冻结。我认为部分问题是我的命令。我不确定我是否可以拥有多个，但是我为每个表创建了一个不同的命令，然后在最后关闭与数据库的连接。我想把它作为一个页面保留，如果可以的话，因为我已经做了很多工作来保持这种方式，但也考虑将它分成多个页面，并且只是在每个页面上发布一个新的sqlcommand。这是代码：

感谢大家的帮助。请原谅我，我是新手，不是专业人士，而是学生。我拿出了ExecuteNonQuery（）;对于每个块，页面将加载，但不会将任何信息保存到数据库。我现在要尝试你的建议，我回到这里，看看你们有什么话要说。

这是您的存储过程：
CREATE PROCEDURE [proSingle]
@firstName varchar(255),
@lastName varchar(255),
@streetAddress varchar(255),
@city varchar(255),
@zip varchar(255),
@phone varchar(255),
@email varchar(255),
@collegeName varchar(255),
@collegeCity varchar(255),
@major varchar(255),
@cGPA varchar(255),
@cGraduate varchar(255), /* carry on making variables for Table HS , Company , Refrence */
AS
BEGIN
INSERT INTO [Applicant] (firstName, lastName, streetAddress, city, ZIP, phone, email)
VALUES (@firstName, @lastName, @streetAddress, @city, @zip, @phone, @email)
INSERT INTO [College] (CollegeName, CollegeCity, Major, CGPA, CGraduate)
VALUES (@collegeName, @collegeCity, @major, @cGPA, @cGraduate)
INSERT INTO [HS] (HSName, HSCity, HSGradYear, HSGraduate)
VALUES (@hsName, @hsCity, @hsGradYear, @hsGraduate)
INSERT INTO [Company] (CAddress, CCity, CState, CZIP, SupervisorName, SupervisorPhone, SupervisorEmail)
VALUES (@cAddress, @cCity, @cStae, @cZIP, @supervisorName, @supervisorPhone, @supervisorEmail)
INSERT INTO [References] (RName, RPhone, REmail, Relationship)
VALUES (@rName, @rPhone, @rEmail, @relationship)
END
现在在您的C＃代码中
SqlConnection conn = new SqlConnection();
conn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["Conn2"].ConnectionString;
string sqlquery = "exec proSingle @firstName, @lastName, @streetAddress, @city, @zip, @phone, @email";
// along with all the other variable you created in stored procedure
SqlCommand command = new SqlCommand(sqlquery, conn);
try
{
// open the connection to the database.
conn.Open();
string FirstName = firstNameTextBox.Text;
// make sure to use @ variable name
command.Parameters.AddWithValue("@firstName", FirstName);
// last name
string LastName = lastNameTextBox.Text;
command.Parameters.AddWithValue("@lastName", LastName);
//add all the Variable as you have been adding but only to command
command.ExecuteNonQuery();
}
catch (System.Data.SqlClient.SqlException exception)
{
string msg = "Some information has not been entered. Please go back and correct information.";
}
finally
{
conn.Close();
}

您应该能够将INSERTS串在一起作为单个命令，具体取决于您的SQL设置，用分号分隔的命令。
string sqlquery = "INSERT INTO [Applicant] (firstName, lastName, streetAddress, city, ZIP, phone, email) VALUES (@firstName, @lastName, @streetAddress, @city, @zip, @phone, @email); INSERT INTO [College] (CollegeName, CollegeCity, Major, CGPA, CGraduate) VALUES (@collegeName, @collegeCity, @major, @cGPA, @cGraduate)";
另一方面，如果你想把它作为一个单独的页面，为什么不为每个insert语句创建一个函数来保持它们完全分开？然后为了调试，尝试一次调用一个函数，然后一次添加一个函数以查看它是否仍然冻结？
