我试图插入一个泛型列表到SQL Server使用SqlBulkCopy,
我有麻烦了机智的标识字段
我婉牛逼我的目标表生成的标识字段我应该如何处理这个问题,这里是我的代码
using (var bulkCopy = new SqlBulkCopy(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
{
bulkCopy.BatchSize = (int)DetailLines;
bulkCopy.DestinationTableName = "dbo.tMyTable";
var table = new DataTable();
var props = TypeDescriptor.GetProperties(typeof(tBFFormularyStatusList))
//Dirty hack to make sure we only have system data types
//i.e. filter out the relationships/collections
.Cast<PropertyDescriptor>()
.Where(propertyInfo => propertyInfo.PropertyType.Namespace.Equals("System"))
.ToArray();
foreach (var propertyInfo in props)
{
bulkCopy.ColumnMappings.Add(propertyInfo.Name, propertyInfo.Name);
table.Columns.Add(propertyInfo.Name, Nullable.GetUnderlyingType(propertyInfo.PropertyType) ?? propertyInfo.PropertyType);
}
var values = new object[props.Length];
foreach (var item in myGenericList)
{
for (var i = 0; i < values.Length; i++)
{
values[i] = props[i].GetValue(item);
}
table.Rows.Add(values);
}
bulkCopy.WriteToServer(table);
}
例外
Property accessor 'ID' on object 'ProcessFlatFiles.DetailsClass' threw the following exception:'Object does not match target type.'
我也曾尝试
using (var bulkCopy = new SqlBulkCopy(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString, SqlBulkCopyOptions.KeepIdentity))
{
