过程或函数期望未提供的参数。的ExecuteNonQuery

Question

所以问题是：

，当我点击我的注册网页表单提交按钮有就行了“oCom.ExecuteNonQuery();”错误（在文本框中添加相应的值之后）。它说

“过程或函数'ADDUSR'期望参数'@useremail'，其中 未提供。”

而且我一直在试图找出为什么它说，因为我仔细检查了与oUsr.Email = "hello@hello.com"，该信息来自调试器，这是有道理的，因为我只是增加它的文本框点击提交按钮之前。

在这里，你有我尝试使用数据库的存储过程：

CREATE PROCEDURE ADDUSR 

@useremail varchar (35), 
@username varchar (30), 
@userpass varchar (30), 
@name varchar (100), 
@phone varchar (20), 
@address varchar (150), 
@authority int, 
@special bit 

AS 
BEGIN 
INSERT INTO USERS 
(
_UserEmail, 
_UserName, 
_UserPass , 
_Name , 
_Phone, 
_Address, 
_Authority, 
_Special 
) 
VALUES 
(
@useremail, 
@username, 
@userpass, 
@name, 
@phone, 
@address, 
@authority, 
@special 
) 
END 

Answer 1

你只犯了一个错误，当你写usermail参数。

变化

oCom.Parameters.AddWithValue("@useremail ,", oUsr.Email); 

到

oCom.Parameters.AddWithValue("@useremail", oUsr.Email); 

，并删除所有逗号你AddWithValue方法。喜欢;

oCom.CommandType = CommandType.StoredProcedure; 
oCom.Parameters.AddWithValue("@useremail", oUsr.Email); 
oCom.Parameters.AddWithValue("@userpass", oUsr.Pass); 
oCom.Parameters.AddWithValue("@name", oUsr.Name); 
oCom.Parameters.AddWithValue("@phone", oUsr.Phone); 
oCom.Parameters.AddWithValue("@address", oUsr.Address); 
oCom.Parameters.AddWithValue("@username", oUsr.Usrname); 
oCom.Parameters.AddWithValue("@authority", oUsr.Auth); 
oCom.Parameters.AddWithValue("@special", oUsr.SpecialK); 

Answer 2

oCom.Parameters.AddWithValue("@useremail ,", oUsr.Email); 
             ^^^^ 

Answer 3

尝试这一个 -

static string connectionString = "Server=.\\SQLExpress;AttachDbFilename=L:\\Apps\\VS Projects\\Carnisoftix\\CarniDb.mdf;Database=CarniDb;Trusted_Connection=Yes;"; 

public static void regUsr(carniuser oUsr) 
{ 
    using(SqlConnection oConnection = new SqlConnection(connectionString)) 
    { 
     oConnection.Open(); 

     using (SqlCommand oCom = new SqlCommand("ADDUSR", oConnection)) 
     { 
      oCom.CommandType = CommandType.StoredProcedure; 
      oCom.Parameters.AddWithValue("@useremail", oUsr.Email); 
      oCom.Parameters.AddWithValue("@userpass", oUsr.Pass); 
      oCom.Parameters.AddWithValue("@name", oUsr.Name); 
      oCom.Parameters.AddWithValue("@phone", oUsr.Phone); 
      oCom.Parameters.AddWithValue("@address", oUsr.Address); 
      oCom.Parameters.AddWithValue("@username", oUsr.Usrname); 
      oCom.Parameters.AddWithValue("@authority", oUsr.Auth); 
      oCom.Parameters.AddWithValue("@special", oUsr.SpecialK); 
      oCom.ExecuteNonQuery(); 
     } 

     oConnection.Close(); 
    } 
}
