根据C＃中列的值转到下一行 [英] Go to the next row depending on a value from a column in C#
问题描述
所以，我正在尝试构建一段代码，我可以根据列中的值将该行插入或不插入数据库。基本上它会检查我试图插入的所有行，看看是否有任何一个带有值列的行，在这种情况下，带有M。
我尝试过：
So, I am trying to build a piece of code where I am able to depending on a value from a column it will insert that row or not into the database. Basically it will check all the rows that I am trying to insert and see if that is any one with a value column, in this case, with "M".
What I have tried:
<pre>for (int linhas = 0; linhas < dataGridView1.Rows.Count; linhas++)
{
if (dataGridView1.Rows[linhas].Cells[8].Value.ToString() != "M")
{
string queryInsert = @"INSERT INTO CIM_Etiquetas(Carga, Referencia, Quantidade, DataEmissao, Linha, Marca, DescricaoWeb, CodProd, TipoEmb, NomePC) VALUES (@Carga, @Referencia, @Quantidade, @DataEmissao, @Linha, @Marca, @DescricaoWeb, @CodProd, @TipoEmb, @NomePC)";
cmd = new SqlCommand(queryInsert);
cmd.Connection = con;
cmd.Parameters.Add(new SqlParameter("@Carga", SqlDbType.VarChar, 11, "Carga"));
cmd.Parameters.Add(new SqlParameter("@Referencia", SqlDbType.VarChar, 30, "Referencia"));
cmd.Parameters.Add(new SqlParameter("@Quantidade", SqlDbType.Decimal, 11, "Quantidade"));
cmd.Parameters.Add(new SqlParameter("@DataEmissao", SqlDbType.SmallDateTime, 11, "DataEmissao"));
cmd.Parameters.Add(new SqlParameter("@Linha", SqlDbType.SmallInt, 4, "Linha"));
cmd.Parameters.Add(new SqlParameter("@Marca", SqlDbType.VarChar, 11, "Marca"));
cmd.Parameters.Add(new SqlParameter("@DescricaoWeb", SqlDbType.VarChar, 150, "DescricaoWeb"));
cmd.Parameters.Add(new SqlParameter("@CodProd", SqlDbType.VarChar, 20, "CodProd"));
cmd.Parameters.Add(new SqlParameter("@TipoEmb", SqlDbType.VarChar, 8, "TipoEmb"));
cmd.Parameters.Add(new SqlParameter("@NomePC", SqlDbType.VarChar, 30, "NomePC"));
cmd.Parameters["@Carga"].Value = dataGridView1.Rows[linhas].Cells[0].Value.ToString();
cmd.Parameters["@Referencia"].Value = dataGridView1.Rows[linhas].Cells[1].Value.ToString();
cmd.Parameters["@Quantidade"].Value = dataGridView1.Rows[linhas].Cells[2].Value.ToString();
cmd.Parameters["@DataEmissao"].Value = dataGridView1.Rows[linhas].Cells[3].Value.ToString();
cmd.Parameters["@Linha"].Value = dataGridView1.Rows[linhas].Cells[4].Value.ToString();
cmd.Parameters["@Marca"].Value = dataGridView1.Rows[linhas].Cells[5].Value.ToString();
cmd.Parameters["@DescricaoWeb"].Value = dataGridView1.Rows[linhas].Cells[6].Value.ToString();
cmd.Parameters["@CodProd"].Value = dataGridView1.Rows[linhas].Cells[7].Value.ToString();
cmd.Parameters["@TipoEmb"].Value = dataGridView1.Rows[linhas].Cells[8].Value.ToString();
cmd.Parameters["@NomePC"].Value = System.Environment.MachineName;
cmd.ExecuteNonQuery();
}
}
如果该行作为具有该值的列，它将跳转到下一行，直到都结束了。你有任何想法我该如何解决？
If that row as a column with that value it will jump to the next row until it's finished. Do you have any ideas how can I solve it?
推荐答案
如果我理解你的问题，你想跳过某一列中有M的行。
更改你的if语句：
If I understand your question, you want to skip rows that have an "M" in a certain column.
Change your if statement from this:
if ((Myrow.Cells[8].Value.ToString()) == "M")
{
//What should I do here?
}
else
{
...对此：
...to this:
if (Myrow.Cells[8].Value.ToString()) != "M")
{
只会在第8列中插入不具有M值的行，并且不会插入如果他们这样做的话，请等待他们。
如果那不是你的意思，请改进你的问题。
This will only insert rows that do not have a value of M in the 8th column, and will not insert them if they do.
If that's NOT what you meant, improve your question.
