DataGridView 数据导出到Excel

86.

87. //建立插入动作的Command

88. mandText = sb.ToString();

89. OleDbParameterCollection param = objCmd.Parameters;

90.

91. for(int i=0;i<cols;i++)

92. {

93. param.Add(new OleDbParameter("@" + dt.Columns[i].ColumnName,

OleDbType.VarChar));

94. }

95.

96. //遍历DataTable将数据插入新建的Excel文件中

97. foreach (DataRow row in dt.Rows)

98. {

99. for (int i=0; i<param.Count; i++)

100. {

101. param[i].Value = row[i];

102. }

103.

104. objCmd.ExecuteNonQuery();

105. }

106.

107. return "数据已成功导入Excel";

108. }

109. // Trackback: /TrackBack.aspx?PostId=754176

九、利用OLEDB，以excel为数据库，把dataset中的数据导入到excel文件中

1. public static void exportToExcelByDataset(string filePath, DataSet

ds,XmlNode node)

2. {

3. string sqlstr;

4.

5. if(fi.Exists)

6. {

7. fi.Delete();
