执行随机SQL查询并将结果输入到datagridview

Question

I am using C# and MySQL

So far I've tried to execute SELECT, INSERT, DELETE commands and display result in datagridview using DataSet and MySqlDataAdapter successfully.

But now I want to 1.execute a random query (whatever user type into a Textbox and press Execute button) and also 2.display result in a datagridview** .

What are these steps needed to archive that task?

(I tried to search but only return me those results in what people are using specific command like SELECT, my case is different, the query is randomly typed by user)

Here is a sample code snippet of binding a query result into a gridview:

DataSet objDataSet = new DataSet();
SqlConnection objConn = new SqlConnection();

SqlCommand objComm = new SqlCommand("SELECT COUNT(*) FROM table", objConn);

SqlDataAdapter objDataAdapter = new SqlDataAdapter(objComm);

if (objConn.State == ConnectionState.Closed)
{
    objConn.Open();
}

objDataAdapter.Fill(objDataSet, strTable);

dataGridView1.DataSource = objDataSet;
