过程或函数Top100指定的参数太多

我正在尝试修复这个旧的asp.net页面，并且不断收到'过程或函数Top100指定了太多的参数。这个错误只发生在你点击'Top 10'按钮时，我不确定该怎么做，因为我对c＃非常陌生。我还不知道我的方式。过程或函数Top100指定的参数太多

public SqlDataReader ExecuteQuery(string strSql) 
{ 
    MsSqlConnection = OpenConnection(); 
    SqlCommand command = new SqlCommand(); 
    command.CommandType = CommandType.Text; 
    command.CommandText = strSql; 
    command.Connection = MsSqlConnection; 
    MsSqlConnection.Open(); 
    SqlDataReader reader = command.ExecuteReader(); 
    return reader; 
}

TOP100代码：

public DataTable Top100(int nation, int class_) 
{ 

    string strSql = "exec DragonRajaDB.dbo.Top100 " + Convert.ToInt32(nation) + "," + Convert.ToInt32(class_); 

    DataTable dt = new DataTable(); 
    dt.Columns.Add(new DataColumn("Rank", typeof(int))); 
    dt.Columns.Add(new DataColumn("Name", typeof(String))); 
    dt.Columns.Add(new DataColumn("Lev", typeof(int))); 
    dt.Columns.Add(new DataColumn("Class", typeof(String))); 
    dt.Columns.Add(new DataColumn("Nation", typeof(String))); 
    dt.Columns.Add(new DataColumn("Guild", typeof(String))); 
    dt.Columns.Add(new DataColumn("GuildLogoURL", typeof(String))); 
    using (SqlDataReader reader = ExecuteQuery(strSql)) 
    { 
     int i = 1; 
     while (reader.Read()) 
     { 
      DataRow dr = dt.NewRow(); 
      dr[0] = i; 
      dr[1] = reader.GetSqlString(0).Value; 
      dr[2] = reader.GetSqlInt32(1).Value; 
      int playerClass = reader.GetSqlInt32(2).Value; 
      switch (playerClass) 
      { 
       case 0: 
        dr[3] = "Warrior"; 
        break; 
       case 1: 
        dr[3] = "Thief"; 
        break; 
       case 2: 
        dr[3] = "Archer"; 
        break; 
       case 3: 
        dr[3] = "Wizard"; 
        break; 
       case 4: 
        dr[3] = "Priest"; 
        break; 
       default: 
        dr[3] = "Unknown"; 
        break; 
      } 
      dr[4] = reader.GetSqlString(3).Value; 
      if (reader.GetSqlString(4).IsNull) 
      { 
       dr[5] = ""; 
       dr[6] = ""; 
      } 
      else 
      { 
       dr[5] = reader.GetSqlString(4).Value; 
       int guildCode = reader.GetSqlInt32(5).Value; 
       dr[6] = "guildlogos/guild" + guildCode.ToString() + ".gif"; 
      } 

      dt.Rows.Add(dr); 
      i++; 
     } 
    } 

    return dt; 
}

下面是存储过程：

USE [Dragonrajadb] 
GO 
/****** Object: StoredProcedure [dbo].[Top100] Script Date: 10/21/2014 11:02:26 ******/ 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 
ALTER Procedure [dbo].[Top100]    
@nation int = 0 


AS    
DECLARE @SQLString NVARCHAR(500)    

SET @SQLString = N'SELECT top 100 name, lev, exp, nation from chr_info where name not in (''GM01'') '    
if @nation <> 0   
begin    
    if @nation = 6   
    begin   
    set @SQLString = @SQLString + ' and nation in (6,22,38,14,30,38)'   
    end   
    else if @nation = 3   
    begin   
    set @SQLString = @SQLString + ' and nation not in (4,20,12,28,36,6,22,38,14,30,38)'   
    end   
    else if @nation = 4   
    begin   
    set @SQLString = @SQLString + ' and nation in (4,20,12,28,36)'   
    end   
end   
set @SQLString = @SQLString + ' order by lev desc, exp desc'    
EXECUTE sp_executesql @SQLString

护理向我们展示了'DragonRajaDB.dbo.Top100'的定义是什么？ – canon 2014-10-10 18:22:35

没有一个？ – user3851593 2014-10-10 18:28:47

...来自数据库。 – canon 2014-10-10 18:31:01

过程Top100只有一个参数，即：nation：

ALTER Procedure [dbo].[Top100]    
@nation int = 0 -- just one parameter 
AS 
...

您正在尝试指定第二个参数：class：

string strSql = "exec DragonRajaDB.dbo.Top100 " + nation + "," + class_;

因此，除去class说法：

string strSql = "exec DragonRajaDB.dbo.Top100 " + nation
