我试图通过一个简单的过程将数据插入到我的数据库中,但是当我单击我的按钮时,我不断返回:'必须声明标量变量“@categoryid”。我可以补充一点,没有变量的另一个数据添加工作没有问题。我在哪里犯了错误?插入类:public partial class B_Line{ public B_Line() { this.Budget_Scheme = new HashSet<Budget_Scheme>(); } public int Line_id { get; set; } public int Category_id { get; set; } public string Name { get; set; } public string Comment { get; set; } public void InsertLine(int categoryID, string name, string comment) { using (var connection = Connection.ConnectionFactory.GetOpenConnection()) { List<B_Line> lines = new List<B_Line>(); lines.Add(new B_Line {Category_id = categoryID, Name = name, Comment = comment}); connection.Execute("dbo.Insert_Line @categoryid, @name, @comment", lines); } }}执行按钮:private void Button1_Click(object sender, EventArgs e){ B_Line lines = new B_Line(); int ID_Kategorii = Int32.Parse(categoryID.Text); lines.InsertLine(ID_Kategorii, nameLine.Text, commentLine.Text);}存储过程 MSSQL:ALTER procedure [dbo].[Insert_Lines](@categoryid int, @name nchar(40), @comment nchar(100)) as insert into BCategory (Category_id, Name, Comment) Values (@categoryid, @name, @comment)
