如何确定使用C＃的SQL Server CE表中是否存在列？

您可以只查询信息模式表以获取所需的信息：

public bool isValidField(string tableName, string columnName){    var tblQuery = "SELECt 1 FROM INFORMATION_SCHEMA.COLUMNS"        + " WHERe TABLE_NAME = @tableName AND"        + " COLUMN_NAME = @columnName";    SqlCeCommand cmd = objCon.CreateCommand();    cmd.CommandText = tblQuery;    var tblNameParam = new SqlCeParameter(        "@tableName",        SqlDbType.NVarChar,        128);    tblNameParam.Value = tableName    cmd.Parameters.Add(tblNameParam);    var colNameParam = new SqlCeParameter(        "@columnName",        SqlDbType.NVarChar,        128);    colNameParam.Value = columnName    cmd.Parameters.Add(colNameParam);    object objvalid = cmd.ExecuteScalar(); // will return 1 or null    return objvalid != null;}
