我一直在做一个 C# 项目,我在其中浏览 Excel 文件并将其查看到 gridview 中。但是,有一条我不明白的错误消息。有人可以帮我解决这个问题。
这是我使用的代码:
private void buttonUpload_Click(object sender, EventArgs e)
{
string connectionString = String.Format(@"Data Source={0};Extended Properties=""Excel 8.0;HDR=YES;IMEX=1;""", textBoxFileName.Text);
string query = String.Format("select * from [{0}$]", "Sheet1");
SqlDataAdapter dataAdapter = new SqlDataAdapter(query, connectionString);
DataSet dataSet = new DataSet();
dataAdapter.Fill(dataSet);
dataGridView1.DataSource = dataSet.Tables[0];
}
这是错误消息:
"A network-related or instance-specific error occurred while establishing
a connection to SQL Server. The server was not found or was not accessible.
Verify that the instance name is correct and that SQL Server is configured
to allow remote connections.
(provider: SQL Network Interfaces,
error: 26 - Error Locating Server/Instance Specified)."
