Question

我编写了一个存储过程
然后我写了C＃代码
```
ds.Tables[0].Rows[0][0].ToString().Split(',')
```
ds是我的数据集，其中包含从ImportData（列SQLQueryName）上面检索的存储过程）

问题是：我为strMendetory使用了字符串数组，我需要从strMendetory中找出存储过程参数的数据类型。当我为它实现代码时，它像往常一样返回System.string（即使它包含DATETIME）。

请给我同样的建议。

存储过程代码：

CREATE PROCEDURE AddDepartments
        @DepartmentName VARCHAR(100),
        @DepartmentCode VARCHAR(100),
        @CompanyLocationID INT,
        @Details VARCHAR(100),
        @Flag BIT,
        @CreatedDateTime DATETIME,
        @MarkDeleted BIT,
        @AccessGroupMasterID INT
AS
BEGIN
    INSERT INTO Departments(DepartmentName, DepartmentCode, CompanyLocationID,  
                            Details, Flag, CreatedDateTime, MarkDeleted, 
                            AccessGroupMasterID)
    VALUES(@DepartmentName, @DepartmentCode, @CompanyLocationID, 
           @Details, @Flag, @CreatedDateTime, @MarkDeleted,
           @AccessGroupMasterID)    
END
GO

INSERT INTO ImportData(ImportItemName, ReferenceTableName, ImportFileName, 
                       SQLQueryTypeID, SQLQueryName, MarkDeleted)
VALUES('Department', 'Departments', 'ImportDepartments.xls',
       2, 'AddDepartments, @DepartmentName, @DepartmentCode, @CompanyLocationID, @Details, @Flag, @CreatedDateTime, @MarkDeleted, @AccessGroupMasterID', 0)
GO

C＃代码：

String[] strMendetory = ds.Tables[0].Rows[0][0].ToString().Split(',');
string columnValue="MynewValuToInsertinProcedure";

for (int columCounter = 1; columCounter < strMendetory.Count(); columCounter++)
{
     cmd.Parameters.AddWithValue(strMendetory[columCounter], columnValue);
}

使用sqlparameter，可以指定sql数据类型。这是代码示例：

            SqlParameter[] param = {
                                        new SqlParameter("@param1", SqlDbType.VarChar, 100),
                                        new SqlParameter("@param2", SqlDbType.Int),
                                        new SqlParameter("@param3", SqlDbType.DateTime)
                                   };

            //@param1, @param2, @param3 should match your parameters name in stored procedure

            param[0].Value = "test"; //pass the value to your parameter here
            param[1].Value = 2;
            param[2].Value = DateTime.Now;

            SqlCommand sqlcmd = new SqlCommand();

            foreach (SqlParameter x in param)
            {
                sqlcmd.Parameters.Add(x);
            }
