有没有人知道可能导致这种情况的原因？
NHibernate中的这一行导致应用程序崩溃。
if（effectiveParameterLocations.Length＆gt; 0）//先前存在的参数
我唯一的猜测是，effectiveParameterLocations没有以某种方式具有Length属性。
该应用程序是一个Web应用程序，NHibernate成功连接到数据库，从一个表中获取一组对象，通过这个代码，同时设置查询它崩溃的下一组对象。
public void ResetParametersIndexesForTheCommand(int singleSqlParametersOffset)
{
// a better place could be the Bind of each IParameterSpecification but we have to do it before bind values
// in this way the same parameter of a dynamic-filter will be set with two different parameter-names in the same command (when it is a command-set).
if (singleSqlParametersOffset < 0)
{
throw new AssertionFailure("singleSqlParametersOffset < 0 - this indicate a bug in NHibernate ");
}
// due to IType.NullSafeSet(System.Data.IDbCommand , object, int, ISessionImplementor) the SqlType[] is supposed to be in a certain sequence.
// this mean that found the first location of a parameter for the IType span, the others are in secuence
foreach (IParameterSpecification specification in Specifications)
{
string firstParameterId = specification.GetIdsForBackTrack(factory).First();
int[] effectiveParameterLocations = SqlQueryParametersList.GetEffectiveParameterLocations(firstParameterId).ToArray();
if (effectiveParameterLocations.Length > 0) // Parameters previously present might have been removed from the SQL at a later point.
{
int firstParamNameIndex = effectiveParameterLocations.First() + singleSqlParametersOffset;
foreach (int location in effectiveParameterLocations)
{
int parameterSpan = specification.ExpectedType.GetColumnSpan(factory);
for (int j = 0; j < parameterSpan; j++)
{
sqlQueryParametersList[location + j].ParameterPosition = firstParamNameIndex + j;
}
}
}
}
}
我认为这是因为DILE -

有问题的表格中填充的对象看起来很正常，并且有六个列都是简单的东西，标准的poco。
生成的查询有1个参数。
爆炸前的查询 -
