private static void SqlBulkCopyData(string[] phone, string smsInfo)

if (phone == null) return;

//生成DataTable
DataTable dataTable = new DataTable();

DataColumn column = new DataColumn();

//qy_id

dataTable.Columns.Add(column);

//Info_ID

column.MaxLength = 32;
column.ColumnName = "Info_ID";
dataTable.Columns.Add(column);

//SP_Port
column = new DataColumn();
column.DataType = System.Type.GetType("System.String");
column.MaxLength = 24;
column.ColumnName = "SP_Port";
dataTable.Columns.Add(column);

//Phone
column = new DataColumn();
column.DataType = System.Type.GetType("System.String");
column.MaxLength = 11;
column.ColumnName = "Phone";
dataTable.Columns.Add(column);

//Content
column = new DataColumn();
column.DataType = System.Type.GetType("System.String");
column.MaxLength = 300;
column.ColumnName = "Content";
dataTable.Columns.Add(column);

//SendTime
column = new DataColumn();
column.DataType = System.Type.GetType("System.DateTime");
column.ColumnName = "SendTime";
column.DefaultValue = DateTime.Now;
dataTable.Columns.Add(column);

//SendLevel
column = new DataColumn();
column.DataType = System.Type.GetType("System.Int32");
column.ColumnName = "SendLevel";
column.DefaultValue = 4;
dataTable.Columns.Add(column);

//IsLong

column.DataType = System.Type.GetType("System.Int32");
column.ColumnName = "AdminID";
column.DefaultValue = 0;
dataTable.Columns.Add(column);

string[] result = new string[phone.Length];

for (int i = 0; i < phone.Length; i++)
{
//生成GUID
string Guid = System.Guid.NewGuid().ToString("N").ToUpper();
string phoneNew = string.Empty;
int phoneType = GetMobileType(phone[i], out phoneNew);
if (phoneType == 0)
{
result[i] = phoneNew + "-0-0";
}
else
{
DataRow dataRow = dataTable.NewRow();
dataRow["qy_id"] = 16;
dataRow["Info_ID"] = Guid;
dataRow["SP_Port"] = "10657027014211";
dataRow["Phone"] = phoneNew;
dataRow["Content"] = smsInfo;
dataRow["IsLong"] = 0;
dataTable.Rows.Add(dataRow);
result[i] = phoneNew + "-1-" + Guid;
}
}

//BCP copy
SqlConnection conn = new SqlConnection();
conn.ConnectionString = "server=.;uid=dmkj_hpc;pwd=#$wlh*&1110h%c;database=DMKJ_SMS";
conn.Open();

SqlTransaction sqlbulkTransaction = conn.BeginTransaction();

//请在插入数据的同时检查约束，如果发生错误调用sqlbulkTransaction事务
SqlBulkCopy copy = new SqlBulkCopy(conn, SqlBulkCopyOptions.CheckConstraints, sqlbulkTransaction);

copy.DestinationTableName = "T_SMS_SendInfo";
foreach (DataColumn dc in dataTable.Columns)
{
copy.ColumnMappings.Add(dc.ColumnName, dc.ColumnName);

}
try
{

sqlbulkTransaction.Commit();

//for (int x = 0; x < dataTable.Rows.Count; x++)

// }

//foreach (string str in result)
//{

} 使用SqlBulkCopyOptions.UseInternalTransaction：

using (SqlBulkCopy bulkCopy = new SqlBulkCopy(
connectionString, SqlBulkCopyOptions.KeepIdentity |
SqlBulkCopyOptions.UseInternalTransaction))
{
bulkCopy.BatchSize = 10;
bulkCopy.DestinationTableName =
"dbo.BulkCopyDemoMatchingColumns";

// Write from the source to the destination.
// This should fail with a duplicate key error
// after some of the batches have been copied.
try
{
bulkCopy.WriteToServer(XXX);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
//some code;
}
}

使用SqlTransaction ：

using (SqlConnection destinationConnection =
new SqlConnection(connectionString))
{
destinationConnection.Open();

using (SqlTransaction transaction =
destinationConnection.BeginTransaction())
{
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(
destinationConnection, SqlBulkCopyOptions.KeepIdentity,
transaction))
{
bulkCopy.BatchSize = 10;
bulkCopy.DestinationTableName =
"dbo.BulkCopyDemoMatchingColumns";

// Write from the source to the destination.
// This should fail with a duplicate key error.
try
{
bulkCopy.WriteToServer(XXX);
transaction.Commit();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
transaction.Rollback();
}
finally
{
//code;
}
}
}
}


SqlBulkCopyOptions

	成员名称	说明
	Default	对所有选项使用默认值。
	KeepIdentity	保留源标识值。如果未指定，则由目标分配标识值。
	CheckConstraints	请在插入数据的同时检查约束。默认情况下，不检查约束。
	TableLock	在批量复制操作期间获取批量更新锁。如果未指定，则使用行锁。
	KeepNulls	保留目标表中的空值，而不管默认值的设置如何。如果未指定，则空值将由默认值替换（如果适用）。
	FireTriggers	指定后，会导致服务器为插入到数据库中的行激发插入触发器。
	UseInternalTransaction	如果已指定，则每一批批量复制操作将在事务中发生。如果指示了此选项，并且为构造函数提供了 SqlTransaction 对象，则发生 ArgumentException。
