将数据插入第 30 列，第 1 行

如何解决将数据插入第 30 列，第 1 行

con.Open(); 

SqlCommand cmd = con.CreateCommand();
cmd.CommandType = CommandType.Text;

string[] col = {
                   "name","dr","WBC","Lympho","Mono","Gran","RBC","Hb","PCV","Platelet","ESR","BloodGroupRh","Striglycride","SChol","SHDL","SLDL","BloodUrea","SCreatenin","SUA","SCa","RBSugar","HBA1c","SGOT","SGPT","ALP","TSB","SerumBhCG","Myoglobin","CK","Trobonin","CRP","AntiCCP","STyphoied IgG","STyphoied IgM","RoseBengal","me","HCV","HBS"
               };
Control[] val = { 
                    textBox1,comboBox1,txt1,txt2,txt3,txt4,txt5,txt6,txt7,txt8,txt9,txt10,txt11,txt12,txt13,txt14,txt15,txt16,txt17,txt18,txt19,txt20,txt21,txt22,txt23,txt24,txt25,txt26,txt27,txt28,txt29,txt30,txt31,txt32,txt33,txt34,txt35,txt36
                };

for (int x = 0; x < col.Length;x++)
{
    cmd.CommandText += "INSERT INTO [Table] (" + col[x] +") VALUES('" + val[x].Text +"')";
    cmd.ExecuteNonQuery();
} 
      
con.Close();

作为显示我有大约 35 列的代码，我尝试使用 for 循环插入它，但是当我运行此代码时，他接下来插入了 35 行，单元格中有许多空值

像这样：

my table after run this code

我想将所有 35 列值放在一行中。

解决方法

SqlConnection con = new SqlConnection(yourConnectionString);
            using (con)
            {
                con.Open();
                string[] col = {
                       "name","dr","WBC","Lympho","Mono","Gran","RBC","Hb","PCV","Platelet","ESR","BloodGroupRh","Striglycride","SChol","SHDL","SLDL","BloodUrea","SCreatenin","SUA","SCa","RBSugar","HBA1c","SGOT","SGPT","ALP","TSB","SerumBhCG","Myoglobin","CK","Trobonin","CRP","AntiCCP","STyphoied IgG","STyphoied IgM","RoseBengal","me","HCV","HBS"
                   };
                Control[] val = {
                        textBox1,comboBox1,txt1,txt2,txt3,txt4,txt5,txt6,txt7,txt8,txt9,txt10,txt11,txt12,txt13,txt14,txt15,txt16,txt17,txt18,txt19,txt20,txt21,txt22,txt23,txt24,txt25,txt26,txt27,txt28,txt29,txt30,txt31,txt32,txt33,txt34,txt35,txt36
                    };

                string col_query = null;
                string columns_in_query = null;
                for (int x = 0; x < col.Length; x++)
                {
                    col_query += x < col.Length - 1 ? +"@" + col[x] + ","+ :+"@" + col[x];
                    columns_in_query += x < col.Length - 1 ? col[x] +","+ : col[x];

                }
                SqlCommand cmd = new SqlCommand("Insert into Table(" + columns_in_query + ") values(" + col_query + ")",con);
                for (int x = 0; x < col.Length; x++)
                   {
                    string value="";
                    if(val[x] is TextBox){
                       value=((TextBox)val[x]).Text.Trim();
                    }
                    if(val[x] is ComboBox){
                       value=((ComboBox)val[x]).SelectedItem.ToStrin().Trim();
                    }
                    cmd.Parameters.AddWithValue("@" + col[x],value);
                }

                cmd.ExecuteNonQuery();
            }

con.Open();

                };

for (int x = 0; x < col.Length;x++)
{
    cmd.CommandText += "INSERT INTO [Table] (" + col[x] +") VALUES('" + val[x].Text +"')";

List < string > values = new List<string>();
foreach(Control c in val)

cmd.CommandText += "INSERT INTO [Table] (" + string.Join(",",col) + ") VALUES('" + string.Join("','",values.ToArray()) + "')";
