您的SQL数据源仅绑定到DATAGRID控件。我看不出您在btnAddUser_Click1事件处理程序中的何处调用以将记录插入数据库。您将需要添加缺少的逻辑，因为现有控件没有连接到该逻辑。你有代码漏洞。您将需要执行与以下内容相近的操作。这只是一个示例，我将其从我的一个数据访问层中取出，并为查看目的对其进行了修改
string _connectionString = string.Empty;
SqlCommand sqlCommand = new SqlCommand();
SqlConnection sqlConnection = new SqlConnection();
._connectionString = config["connectionString"];
sqlConnection.ConnectionString = "<your connection string>";
sqlCommand.Connection = sqlConnection;
sqlCommand.CommandType = CommandType.StoredProcedure;
//add your parameters here
sqlCommand.Parameters.Add("@ParameterNameWithinProcedure", <your value goes here>);
sqlCommand.Parameters.Add("@ParameterNameWithinProcedure", <your value goes here>);
sqlCommand.Parameters.Add("@ParameterNameWithinProcedure", <your value goes here>);
//Repeat for each parameter in your record.
int returnVal = 0;
sqlCommand.CommandText = "< insert record stored procedure name"
try
{
sqlConnection.Open();
using (sqlCommand)
{
returnVal = sqlCommand.ExecuteNonQuery();
}
}
catch (Exception ex)
{
//possibly put some logging inforaation here
}
finally
{
sqlConnection.Close();
}
if(String.IsNullOrEmpty(txtUserName.Text)){//...}
这是一个减少代码的漂亮的小方法。您的SQL数据源仅绑定到您的DATAGRID控件。我看不出您在btnAddUser_Click1事件处理程序中的何处调用以将记录插入数据库。您将需要添加缺少的逻辑，因为现有控件没有连接到该逻辑。你有代码漏洞。您将需要执行与以下内容相近的操作。这只是一个示例，我将其从我的一个数据访问层中取出，并为查看目的对其进行了修改
