无法在数据绑定（gridview）中将类型'string'隐式转换为'bool'

Question

这是将String分配给布尔属性的行：

chkreputative.Checked = gvmanufacturers.DataKeys[rowindex]["IsReputative"].ToString();

Answer 1

摆脱ToString()电话，并应用正确的演员表。您正尝试为String值分配Boolean值，这就是您获得例外的原因。

根据DataKeys对象的类型，您可以尝试以下某些操作：

chkreputative.Checked = (bool)gvmanufacturers.DataKeys[rowindex]["IsReputative"];

chkreputative.Checked = Boolean.Parse(gvmanufacturers.DataKeys[rowindex]["IsReputative"]);

chkreputative.Checked = Convert.ToBoolean(gvmanufacturers.DataKeys[rowindex]["IsReputative"]);
