當(dāng)我在插入數(shù)據(jù)的時(shí)候會(huì)報(bào)如下錯(cuò)誤：

NHibernate: INSERT INTO People (FirstName, IrType) VALUES (@p0, @p1); select SCOPE_IDENTITY();@p0 = 'Cheng', @p1 = '0000AA'
TestCase 'NHDemo.Test.NHibernateSampleFixture.GetCustomerByIdTest'
failed: System.IndexOutOfRangeException : Invalid index 4 for this SqlParameterCollection with Count=4.
at System.Data.SqlClient.SqlParameterCollection.RangeCheck(Int32 index)
at System.Data.SqlClient.SqlParameterCollection.GetParameter(Int32 index)
at System.Data.Common.DbParameterCollection.System.Collections.IList.get_Item(Int32 index)

此處異常顯示: N = 4, 那就是配置文件的第4行有問(wèn)題, 可以簡(jiǎn)單的先注釋第4行做測(cè)試.

這里只啟一個(gè)開(kāi)頭的作用, 具體的錯(cuò)誤,根據(jù)自己的實(shí)際情況來(lái)解決.
